RS PRO Psychrometer, +100 °C, 100 % RH Max, ±2 % Accuracy, Backlit LCD Display, Battery-Powered

Introducing the RS PRO Psychrometer, a highly reliable device used to quickly and effectively measure the relative humidity in the atmosphere. The RS PRO digital psychrometer features two thermometers, one that is placed into liquid (wet bulb) and the other is exposed to the immediate atmosphere (dry bulb) in order to calculate the level of relative humidity in the atmosphere. The backlit LCD display allows clear and accurate readings and the unit can be used for a variety of applications like measuring 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. It is an essential piece of equipment in the HVAC industry, used for inspection and maintenance purposes.

A psychrometer is a type of hygrometer and is an instrument that is used to measure the relative humidity in the atmosphere. 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 analogue units and others can contain a probe for more detailed investigation and measurement in harder to reach areas. Hygrometers 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

A psychrometer is a type of hygrometer device and is a piece of equipment that measures humidity by measuring the water vapour in the air, as well as ambient temperature. It is a dual-purpose unit that can be used to measure and monitor the air quality of the surrounding areas.

A psychrometer 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.
