The rubber grip prevents slippage.
It is somewhat less competitive compared to other products.
A refractometer with good portability and accuracy, for various applications.
The ordinary man on the street may not have use for a refractometer, but a veterinarian, lab technician, gemologist, marine biologist, or even wine grape growers, homebrewers, beekeepers and those who own an aquarium will surely benefit from keeping this type of device handy. This field or laboratory device measures the index of refraction of a sample solution. What distinguishes the best refractometer from a run-of-the-mill device?
A suitable type for your needs
A refractometer can be one of different types. It can be a standard handheld refractometer, a digital handheld refractometer, an Abbe or laboratory refractometer, and an inline process refractometer. For the measurement of the refractive indices of different gases, a Rayleigh refractometer is typically used. There are also automatic refractometers that measure a sample’s refractive index automatically, which is done based on the determination of the critical angle of total reflection.
A traditional or standard handheld refractometer is an analog device that measures the refractive index of a sample liquid. It employs the critical angle principle that governs the way a lens or prism projects a shadow line onto a small reticle made of glass located inside the refractometer. The shadow line is then viewed through a magnifying eyepiece. The sample is placed between the small cover plate and measuring prism. The light channeled through the test sample is either totally reflected internally or passed directly to the reticle.
The reading is taken where a shadow line forms between the lighted and dark area and crosses the scale. You will want a handheld model to have automatic temperature compensation because refractive index is highly temperature dependent.
A digital handheld refractometer operates like a traditional handheld one by utilizing the critical angle principle. The difference lies in the way a LED light source focuses light on a prism component or the underside instead of being channeled through a reticle or being totally internally reflected.
A digital handheld refractometer may be more precise than a traditional handheld model but may be less precise compared to a benchtop unit. A relatively large quantity of sample solution may also be required because it will not be spread thinly against the refractometer prism. Various units of measurement may be used to display the result and they include Brix, concentration, boiling point, Plato units or specific gravity, freezing point and others. The refractometer that a brewer would use is the same type that a fruit grower also uses to measure the concentration of sugar in their harvest to see if the fruits are ripe enough. This is called a Brix refractometer, and it measures 0 to 30 Brix or 1.000 to 1.120 specific gravity, which is a very useful range for home brewing purposes.
For just such a purpose, steer clear of models containing electronic components or that measure battery acid or some other chemical substance. Refractometers that measure battery acid or other chemical solutions will require the use of available equations for conversion to Brix, aside from likely measuring the incorrect range of refractive indices.
Brix refractometers measure the concentration of sucrose in a water and sucrose mixture to find the index of refraction of the sample being tested. Refractometers in the automobile maintenance industry measure the concentration of coolant and the pH value of the coolant oils used in the CNC machining process. Most models come with a sample well made of metal, which is positioned around the prism so it will be easy to clean off a sticky sample such as honey.
An Abbe refractometer is a benchtop instrument that offers high-precision measurement of the index of refraction. The liquid sample is placed into a thin layer sandwiched between a refracting and an illuminating prism. Projected through the illuminating prism is the light source, and a detector mounted on the refracting prism back side shows a dark and light region.
An inline process refractometer is geared for the continuous measurement of a fluid flowing inside a tank or through a pipe. This type of instrument comprises a sensor mounted inline with the flow of fluid and connected to a control box, which typically provides a digital readout along with relay outputs for controlling valves and pumps and 4-20mA analog outputs. The sensor is not placed inline of the process but in a bypass linked by a thin tube. You can look here to find borescopes in case you need to explore those tubes.
Useful features for measurement
Automatic Temperature Compensation (ATC) proves to be useful but not a strict necessity if you own a temperature compensation chart. Models that don’t feature ATC will require the temperature compensation to be optically performed and not just as an electronic effect. A good cheap refractometer will still provide an accurate reading despite the absence of ATC since only the instrument’s temperature is important because you will only need a small quantity of sample compared to the mass of the device itself.
That being said, premium quality refractometers use ATC as a selling point to enable them to report the same value across a wide range of practical temperatures, generally between 13 and 29 degrees Celsius or 55 and 85 degrees Fahrenheit. ATC becomes a worthy feature to have in your device as a couple of drops of even boiling wort can cool quickly to within that range, giving all-grain brewers a specific advantage for monitoring the runoff gravity typically around 170 degrees Fahrenheit. ATC enables you to use the reading you obtain.
The best digital refractometer comes with software to avoid reading interferences due to excessive ambient light. Shading the prism area prevents interference as well. Some models come with dual or multiples scales. They have the capability of inputting a special scale using conversion information that is known. Some digital handheld units are IP65 rated to signify they are water resistant, so you can wash them under running water.
Easy to calibrate and use
Compared to a hygrometer that simply floats in the solution you’re testing, a refractometer is really not as simple to use. The refractometer makes it tricky to calculate the final gravity adjustment. It pays to know what you’re getting when you buy a refractometer. You will also need to calibrate the refractometer prior to use. Fortunately, calibrating most refractometers is simply done using a sample of distilled water. Most units also come with a calibration screw or knob that enables setting to zero. This is what you will need to do: adjust the refractometer to zero while distilled water is in it. You may need to make a few tries to succeed in this process. For precise readings, you also need to calibrate the device using a wort sample with known specific gravity.
To test a sample, all you need to do is open the sample plate, ensure it is clean and dry, and add a few drops of the test solution. Close the sample plate, making sure there aren’t any air bubbles, and then hold up the instrument against a natural light source. It should be easy to read the instrument as well simply by reading straight from the sight scale, with the reading most often in percent/degrees Brix or refractive index (RI).
