Description
Room humidity and temperature sensor
HYGRASGARD® RFTF
Quality product for HVAC sector, accuracy 3 % r.H.
It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, in interior rooms, such as living rooms, offices, hotels, engineering rooms, meeting and conference facilities. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. Fine adjustment by the user is possible.
