Top Rated Scales & Balances – Ratings & Comparison in 2024


In the course of a single day, we weigh things at least more than once. People on a diet always have a bathroom scale on which they stand on every morning just to find out how far they have come into their fitness routine. Before breakfast, those who count their calories literally do so by weighing out what they eat into a bowl of cereal. The letters or parcels we send are weighed by Post Office personnel. The items you buy from the grocery store will be paid for according to how much they weigh. Why, even in some countries, the value of your money is determined by a system of weight. Take for instance the Irish and British pounds that used to weigh exactly a pound. With the way much of the world is driven by weight, people need something as scientifically accurate and precise as scales and balances to do the weighing task.

How to choose the best scale/balance


People who check out the best scales reviews do not necessarily do so because they are on a diet, in much the same way that people who read the best balances reviews are not always grocery store or farm owners or employed in a chemical laboratory. Scales and balances serve a wide range of functionalities in the modern world. How do you make sure you have the best scales and balances for your needs?

Suitability to your purpose

A weighing scale is engineered to measure the weight of an object. Often used to measure a person’s weight, weighing scales are also used in various commercial and industrial applications including measuring the weight of items from a feather to a loaded tractor-trailer. The force, such as the force of gravity, exerted on a mass by a towing vehicle or that of a person’s grip can be measured using a spring scale. Generally measured in newtons, with one newton equivalent to the weight of a mass of around a tenth of kilogram, this force is roughly equal to the weight of an apple. Spring scales are more appropriately called Newton meters since they are employed for measuring newtons. Spring scales operate based on Hooke’s law, which states that the force required to extend a spring is directly proportional to the distance the spring stretches from the at-rest position. This is why the markings on a spring scale are spaced equally apart.

The strongest and hardiest type of scale is the floor scale, which is used to weigh remarkably heavy loads. Employed for a wide range of industrial solutions, floor scales have a low profile and offer weighing ranges between 500 kilograms to over 10,000 kilograms. Used for different industrial weighing applications, floor scales are utilized in veterinary farms, labs and clinics. Considered the second best in load handling, platform scales are used for medium shipments and the air cargo industry in which a moderate flow of weight is common. Platform scales are used in supermarkets, shops, timber enterprises and other small scale industries for measuring approximately between 1000 to 5000 kilograms. Electronic platform scales offer multi functionality using load cells of high accuracy and built-in microprocessors. If you are after affordability and functionality, bench scales offer a good fusion of both. Bench scales go well in the receiving and shipping dock, post office and courier sorting offices, goldsmithing and others thanks to their compact frame and size.

You can also choose between analog and digital scales. Analog models do not run on electricity or batteries. Fewer components mean less likelihood of breakage or damage to working parts. Digital scales offer greater accuracy than analog ones, with many able to display ounces or increments of ounces. Digital scales run on electricity or batteries.
The beam or equal arm balance uses a lever and a uniform bar or the beam suspended at the exact center of that lever on a knife-edge positioned at right angles to it. The fulcrum denotes the point of support and equidistant to it are two pans of equal weight suspended from the beam. The midpoint is the uniform bar’s center of gravity, with the beams supporting the pans in equilibrium. A form of equal-arm balance is the platform balance where two platforms are attached to the beam’s top side, one at every end. A weight or rider is mounted on a bar with a calibrated scale and parallel to the beam while carrying the supports for the two platforms.

An unequal arm balance has the beam hung at a very short distance from one of the unit’s ends. The item to be weighed is positioned at that end while a small known weight is adjusted to that specific point at which balance is achieved on the longer arm. Determining the unknown weight is done by utilizing a formula using the known weight and the distance of each weight from the midpoint or fulcrum. The steelyard is one example of an unequal arm balance

The spring balance features a coiled spring mounted at one end to a support and with a hook at the other, where the object to be weighed is positioned or suspended. The distance through which the spring is stretched is directly proportional to the weight of the object, while adhering to the limit of elasticity of the spring itself. You can read the weight reading based on the conversion of this distance by the graduated scale and pointer attached to the spring.


Reliable accuracy and range

Of primary importance is the accuracy of a scale or balance. There has to be automatic zero calibration to zero out the starting weight. Adjusting to start exactly at zero should be doable. A digital scale should be programmed to zero calibration right from the factory and with nothing placed on it. Accuracy can be influenced by the positioning of the unit. Readouts tend to be off if the surface on which the scale is placed is uneven and the scale’s sensors may be thrown off if the unit is placed on a carpet or bath mat of any thickness. When using the scale on a carpeted surface, make sure it has adjustable feet that lift the sensors away from the soft surface.

The range refers to the limit at which the scale can measure. Older versions of home use scales have a limit of 300 pounds while being less accurate at measuring over 250 pounds. On the other hand, newer scales can come with ranges up to 650 pounds or greater.


If you primarily use a weighing scale to track your progress in your weight loss program, you will want to be able to read the results of your weigh in effortlessly. With most weighing scales positioned on the floor and the user standing, the numbers should be easy to view, so big and bright number displays are a must. Digital scales feature large electronic characters that can be read five or six feet away, while spring-operated models show numbers in increments of 10 plus small hash marks to indicate individual pounds.

Types of scales & balances


There are many types of measuring meters on the market. We have decided to discuss only those types of meters that have found their way readily into our lives on a quotidian basis. Since the average consumer has no use for large weighing scales, we decided to feature only those types of scales that have influenced how we weigh things in general. We have also based our choices on the best ones in each category according to how different types of products have been featured in expert review sites because of their performance, functionality, accuracy and easy readability, and according to actual owner feedback.


Digital pocket scales


Digital pocket scales are designed with a small and compact frame while offering incredible accuracy. Much too small for weighing people, pocket digital scales are found in most hobby shops and some large department stores. They are available from department stores, electronics suppliers, specialty scale sellers and online marketplaces. The most common use of this type of scale is for postage applications to ensure that parcels and letters are not too heavy for posting. A postal scale provides the overage charge should a package or letter weigh more than the first class amount.

Digital pocket scales are also used in model building, which requires utmost precision and exact balance in the model building components. Jewelry digital scales are used to determine the carat weight of gems. They are designed for three weightable materials: precious metals, such as gold, silver and platinum; precious stones including sapphires, rubies and diamonds; other metals such as brass, copper and pewter. Food pocket digital scales are ideal for those who watch what they eat, with some models also able to evaluate calorie information. They enable nutritionists and culinary professionals to measure the quantity of ingredients that have to be added to recipes.



Analytical balance scales


The analytical or lab balance is designed to measure a small mass using the sub-milligram scale. It comprises a measuring pan placed inside a transparent housing called a draft shield, which is outfitted with doors to keep out the dust as well as the air currents in the room to ensure that those elements do not affect measuring operations. Weighing in an analytical balance requires that the sample is at room temperature, which ensures the absence of natural convection that tends to form air currents inside the enclosure, which can cause reading errors. Electronic analytical scales quantify the force required to counter the mass being weighed instead of utilizing actual masses. These types of instruments need calibration adjustments to offset gravitational differences. An electromagnet is used to generate a counteracting force to the sample being measured to achieve balance. Some models come with internal and external calibration along with connectivity to computers and printers. Those that come with stability filters are designed to compensate for drafts, vibration changes and temperature.



Mechanical balances


Essentially consisting of a rigid beam that moves around on a horizontal central knife-edge serving as the fulcrum, the mechanical balance has two end knife edges positioned equidistant from the center and parallel to each other. The items for weighing are placed on pans suspended from bearings. The best mechanical balance is designed with two or more other knife-edges mounted between the pan and the end bearing. One serves to prevent instability of the plane while the other fixes the center of the load at a specific point on the end knife-edge. To prevent damage during the loading process, the scale uses an arresting mechanism that separates the knife-edges from their bearings. A pointer attached to the beam and passing by reflection from a mirror mounted on the beam to a non-proximate scale or passing over a graduated scale indicates the deflection of the instrument. During the 20th century, the electronic balance was developed and it depended on electrical compensation instead of mechanical deflection.



Moisture analyzers


Covering a range of methods for determining moisture content in both trace and high level amounts, moisture analysis can be used for solids, liquids and gases. Highly useful in commercial food production, a moisture analyzer measures moisture in percentage quantities to assist in quality assurance and manufacturing processes. Professionals in the pharmaceutical, plastics and heat treatment industries trace moisture in solids for control, while liquid and gas measurement methods are vital to hydrocarbon and dry air processing as well as for bulk pure gases, pure semiconductor gases, dielectric gases including those employed in power plants and transformers, and pipeline transport of natural gas.

An online or inline moisture analyzer determines the dry mass remaining after a drying process employing infrared energy is used on the original matter that has been weighed previously. This way, humidity can be calculated relative to the weight of the wet matter. The display shows the eliminated moisture in the material during the drying process. This also gives an idea of the consistency or fixed and volatile substances with incredible accuracy.



Spring scales


Primarily designed for industrial applications, a spring scale is commonly used in science education as a basic accelerator. It can be used when accuracy can be compromised to achieve affordability, strength and simplicity while weighing. A spring balance measures weight by going against the force of gravity using the force of an elastic string that is extended. A spring is fixed at one end while a hook that attaches to the object to be weighed is at the other end. A spring scale only measures weight and not mass.

Calibrating a spring balance to ensure accurate mass measurement is performed in the location in which it is used. Do bear in mind that the spring in the scale can end up permanently extended because of repeated use. The spring scale is able to read correctly in settings where the spring axis acceleration is constant. When two or more spring balances are suspended one below the other, each of them will give approximately the same readings, which corresponds to the full weight of the object suspended on the lower scale.



Carat scales


A carat scale offers absolute precision for the jeweler to ascertain the genuine value of gemstones and diamonds. It should offer trustworthy, accurate and repeatable results since you have to deal with precious materials that come with high prices. You need to invest in a premium quality carat scale to ensure continuity of your business through the years. You and your customers should enjoy peace of mind that what is weighed on the scale is exact, accurate and reliable on value.

A carat scale should boast a top rated housing with protective cover and genuine overload protection for resilience against rough treatment. You want the scale to have no ridges to ensure effortless cleaning after use along with effortless retrieval of items that have been inadvertently scattered during the weighing process. You also want the instrument to have a compact footprint and a handy shape so it won’t eat up a lot of counter space and always be easy to handle. Choose from battery- or DC-operated models for versatility in power source.



The difference between scales and balances


The weighing scale is an instrument used to determine the mass or weight of an object by measuring those parameters. On the other hand, a balance compares the torque in the arm component using the sample weight against the torque on the arm and takes this against a standard reference weight that uses a horizontally positioned lever. While a weighing scale measures the weight of an object, a balance measures its mass. There was a time when equal-arm balances were employed in which the weight was placed on one side and an object was put on the other side. The mass between the two items were compared.

Nowadays, it’s not unusual to find balances used as scales for measuring an object’s weight. Contemporary terminology would designate a balance as a scale equipped with greater resolution. A balance comes with features such as counting, mass unit conversion, limit functions for checkweighing and specific gravity weighing. Scales feature tare, gross, printing, net indications and conversion from one unit of measure to another. Today, we have baby scales, food scales, jewelry scales, postal scales, hanging crane scales, luggage scales, weight scales, mini scales, livestock scales, industrial digital scales and wheelchair scales. The variety of balances range from analytical, college, hook, compact, jewelry, to household, laboratory, pallet, pharmacy, platform and water resistant models.


The use of balances and scales in scientific studies


In the laboratory, professionals and students of science often have to measure the mass of different objects under study, and this must be done with utmost precision. To ensure a high degree of precision, laboratory balances are used. Whether using a laboratory balance or scale, the measuring instrument has to deliver extreme readability and accuracy aside from having a broad weighing range. This enables the lab technician or student to develop techniques that allow effortless transfer of material samples from one receptacle to another while making sure that the amount transferred is exact up to one-tenth of a milligram or one ten-thousandth of a gram (±0.0001 gram).

Laboratory scales and balances are equipped with a beam that moves against a frictionless fulcrum. It also has a pointer attached to the beam and that magnifies deviation from the balance position. Fractional weights are utilized or applied along the measuring arm of the beam. Typically, the weighing pan is sealed to prevent dust, drafts and other contaminants from influencing the final measurements made on the balance or scale. Samples of materials have to be kept at room temperature so that air currents or convection does not disturb the material in the housing to prevent inaccurate readings. Laboratory balances can also have errors in reading due to seismic disturbances, friction, buoyancy, misalignment, improper calibration, misalignment, evaporation, condensation and gravitational abnormalities.

The manufacturer of the balance or scale has to use Good Weighing Practice™ (GWP™), a global weighing standard that applies to both existing and new weighing instruments used in any work setting or sector. Analog displays can feature a needle while digital displays have an LED, LCD or vacuum fluorescent display. The interface for the laboratory scale or balance may be one of four types: parallel, serial, universal serial bus (USB) and wireless. The scale or balance also has to conform to ratings prescribed by Ingress Protection (IP) standards, certification by the National Type Evaluation Program (NTEP) and ratings from the National Electronic Manufacturers Association (NEMA). Units sold on the European market should meet the standards set by the Waste Electrical and Electronics Equipment (WEEE) stipulation from the European Union (EU).
