The RH2 Thermohygrometer is an extremely accurate thermohygrometer, with exchangeable external sensors for use in a wide range of measurement applications. It is suitable for laboratory environments, testing synthetic granules and for climate and environment applications.

By selecting from the different available sensors, the range of applications goes from the measurement of air humidity to the determination of relative material moisture via material moisture sensor to the determination of water activity value in diverse food products.

The RH2 could also be connected with a infrared (IR) temperature sensor for temperature measurement from a distance without contact with the object or with a CO2 (carbon dioxide) sensor to measure the quality of air environments such as classrooms, meeting rooms, laboratories or greenhouses.

The RH2 Thermohygrometer measures relative humidity, absolute humidity, dew point, equilibrium moisture content, aw-value, CO2 concentration (ppm) and temperature and provides a manual & automatic data logging feature.
