Product Detail

HYGRASGARD® AAVTF-U (LCD)

The universal HYGRASGARD® AAVTF humidity measuring transducer supports six output values and serves to determine diverse measurands in humidity measuring. Measurands include relative humidity and ambient air temperature. These measurands are used to calculate various parametres internally.
The transmitter has been designed for operation in pollutant-free, non-precipitating air with neither above-atmospheric nor below-atmospheric pressure at the sensor. Application examples include medical, refrigeration, air conditioning and cleanroom engineering. The sensor device is suitable for wall installation.
