HYGRASGARD® AFTF-SD-Modbus

Quality product for the HVAC sector, accuracy ± 2 %
Calibratable outdoor humidity and temperature sensor HYGRASGARD® AFTF - SD - Modbus with Modbus connection, terminal box housing made of impact-resistant plastic, housing cover with quick-locking screws, optionally with/without display.

The universal surface-mounted sensor is used to determine various humidity measurement parameters. The relative humidity and the temperature of the ambient air are measured. Various parameters are calculated internally from these measured variables. The following parameters can be queried via Modbus: relative humidity [% r. H.], absolute humidity [g/m³], mixing ratio [g/kg], dew point temperature [°C], enthalpy [kJ/kg] (disregarding atmospheric air pressure) and ambient temperature [°C].
It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, hotels, technical rooms, assembly and conference facilities. The transmitters are designed for the precise measurement of temperature and humidity. A digital, long-term stable sensor is used as the measuring element for humidity and temperature. Fine adjustment by the user is possible.
