Description

Duct humidity and temperature sensor HYGRASGARD® KFTF - Modbus
Quality product for the HVAC sector, accuracy ±3% or ± 2%
The measuring transducers are used in non-aggressive, dust-free environments, in refrigeration, air conditioning and cleanroom engineering, hotels, engineering rooms, meeting and conference facilities. They provide precise detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature. Fine adjustment by the user is possible. The sensor is suitable for ceiling and duct installation or for integration in equipment.
