UR Air humidity sensor
URV Air humidity sensor with fan

UR Relative Air Humidity Sensor DESCRIPTION
Sensor for relative air humidity measurement at low power (<0.1 W), compact and sturdy, made of anodized aluminum alloy for protection against salt and oxidizing agents. According to WMO norms for environmental monitoring.

Very fast and precise, linear on full range of measure, easy to interface with any data logger. Product for both natural ventilation and forced ventilation. The sensor is equipped with electrical protection and is available with different signal outputs, normalized voltage or current 0 - 1Vdc, 4 - 20mA or RS485/Modbus. Available also combined temperature-humidity (model UTA).
