One of the first things you will notice about this particular hygrometer is the large display with backlight that allows anyone, even seniors with bad eyesight, to read the numbers with ease.

Accuracy is essential for any measurement tool, and this model provides excellent, precise readings that are updated every 10 seconds.

You will appreciate the fact that you will get some extras, such as trends for the readings displays so that you can decide on what measures to take.

Users love that they can put this unit anywhere they like, as it sits comfortably on any flat surface, but it can also be mounted on a wall or attached to a fridge or anything similar with the help of the magnet in the back.

Another thing you may like about it is that you can pick whether you want the temperature to be displayed in Fahrenheit or Celsius.

In-depth information


This hygrometer is very handy and convenient for your home, as it shows both temperature and humidity. Due to its large design, it displays the numbers in such a manner that even someone who normally experiences troubles reading LCD screens can do so. The fact that the screen is backlit helps, too; when you want to read the hygrometer in the dark, you will be able to do so without having to turn on the lights. Users are in love with the touchscreen display that is extremely convenient.

Accuracy is, most probably, something you desire in a measuring unit, like this one. You will be glad to learn that this model is appointed with professional-grade sensors, which means that the values you will be reading are precise. Once you learn such details as temperature and humidity values, you can take the necessary measures to ensure that the climate in your home is ideal.

There is some extra information that this hygrometer provides that you will be pleased to learn about. For instance, you will be able to learn about the high and low records over a 24-hour period, or over the entire time you have been using the unit. Even more, you will be informed of different trends, which will allow you to make the required changes to get to the desired temperature and humidity.

You will get the most accurate readings possible, as the model has an error of maximum 1F or 1C, give or take. The temperature range goes from -58F to 158F. In Celsius, that means between -50C and 70C. As you can see, your measuring tool covers all the possibilities. The humidity range goes from 10% to 99%.

Known Issues


While the touchscreen is a feature many users enjoy, there are some who say that they would have liked a tactile button for adjusting the light.

Another thing noticed by a buyer is that the humidity indicator states that 35% is still comfortable, while it should be considered dry by all standards.
