Quality product for HVAC sector, accuracy 3% r.H.
The calibratable outdoor humidity/temperature sensor HYGRASGARD AFF-LC / AFTF-LC measures the relative humidity and/or the temperature of the air. It converts the measurand into a standard signal of 0 - 10 V or 4...20 mA, is available with/without optional display, with terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking screws.

It has four switchable temperature ranges and is applied in non-aggressive dust-free atmospheres in refrigeration, air conditioning, ventilation and clean room technology. Relative humidity (in % r. H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. These measuring transducers are designed for exact detection of humidity. A digital long-term stable sensor is used as measuring element for humidity measurement. Fine adjustment by the user is possible.
