RS PRO RS-72TH Handheld Thermohygrometer, ±3.5 %RH Accuracy, +60°C Max, 100%RH Max

Introducing the RS PRO handheld thermohygrometer. This high-quality thermal hygrometer is ideal for continuous monitoring and measurement of relative humidity (RH) and temperature for indoor climates. This lightweight and easy to use unit from RS PRO is a great instrument for monitoring the general indoor air quality and can also be used to keep an eye on problem areas for further investigation. The Bluetooth functionality makes it easy to pick up readings via the app on a smartphone, displaying clear and accurate readings and the unit can be used for a variety of applications like observing ambient air temperatures in laboratories, especially during experiments, assessing indoor air quality (IAQ) or even just at home to maintain optimum comfort levels and good indoor air quality.

A thermohygrometer is a dual-purpose instrument that is used to measure temperature and relative humidity. It is an important tool to measure these two variables to ensure good air quality and optimum comfort levels. Proper humidity control can have a wide range of health benefits for people who suffer from skin problems, asthma, allergies, and much more. Some units are available as digital or analogue units and others can contain a probe for more detailed investigation and measurement in harder to reach areas. Thermohygrometers are invaluable for facility maintenance and utility technicians, HVAC-service contractors, and specialists who assess indoor air quality (IAQ) and are widely used at home, in schools, the workplace, hotels, storerooms and many more. The most common applications these units are used for are:

• Test and Measurement


• Industrial Maintenance


• Safety


• Metering


• Maintenance and Repair


• Facility Maintenance


• HVAC


• Temperature

Yes, this is suitable for indoor use as well as outdoor use. It is advised that if the device is being used outdoors, it is used in sheltered areas only as water ingress from outdoor elements could damage the unit and compromise the accuracy.

A thermohygrometer is a device that measures moisture in the immediate air where it is situated, whereas a moisture meter is a device that measures the moisture content held within an object, like a wooden panel, cardboard, etc.

A hygrometer unit measures humidity from moisture in the air in the form of the water vapour that is present in the immediate area. A hydrometer is a device that measures the density or specific gravity (SG) of a liquid by floating in the liquid.
