Quality product for HVAC sector, accuracy ± 3 %calibratable outdoor humidity and temperature sensor HYGRASGARD® AFTF - LC - Modbus with Modbus connection, terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking screws, with ⁄ without optional display.The universal on-wall sensor is used to detect various parameters in humidity measurement. The relative humidity and temperature of the ambient air are measured. These measurands are used to calculate various parameters internally. The Modbus can be used to retrieve the following parameters: relative humidity [% r. H, absolute humidity [g ⁄ m³], mixture ratio [g ⁄ kg], dew-point temperature [°C], enthalpy [kJ ⁄ kg] (ignoring atmospheric air pressure) and ambient temperature [°C].It is used in non-aggressive, dust-free environments, in the refrigeration, air conditioning and clean room technology, 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.
