RH2 Laboratory, climate and environment + aw-value measurements
Climate precision humidity analyzer with data logger for laboratory, climate and environmental applications as well as aw-value measurements / long-term stable humidity and temperature sensors / different sensor types separately selectable / auto data logger up to 10,000 values with measuring location description / lifetime support
Many industrial and commercial companies attach great importance to conscientious and accurate control of the indoor climate to ensure quality. With the Humimeter RH2 thermohygrometer and climate meter you can measure the indoor climate quickly and accurately.
The data logger integrated in the RH2 automatically determines the absolute and relative humidity as well as the dew point and additionally outputs information on the ambient or probe temperature.
The RH2 is simply placed in the room and after a short adjustment time the measured values can be read. Long-term room climate monitoring or similar applications can be carried out with the integrated data logger.
The Humimeter RH2 proves itself with its precise measurements not only in the laboratory, but also in warehouses or production halls for indoor climate monitoring. Random checks or representative long-term measurements are possible.
The use of external sensors opens up further applications and areas of use for relative humidity or dew point determinations with the Humimeter RH2.
Application area
The Humimeter RH2 is a high-precision climate meter and thermohygrometer with integrated data logger for measuring temperature and humidity. It can be used in many applications where precise control of the room climate is necessary, such as plastic granulates, butter, fruit mixtures, spices, granulates, mushrooms and xylitol.
The RH2 has already proven itself in numerous climate and environmental applications and is equipped with innovative sensor technologies for indoor climate monitoring and environmental applications.
