Sensor for measuring of temperature and humidity in ventilation ducts.
The sensor measures the temperature of the air in the duct by a NTC sensor and humidity by a humidity sensor.
The sensor must be turned in such a way that the humidity sensor faces downwards (and the NTC sensor consequently faces upwards) – thereby ensuring that condensate, if any, does not rest on the humidity sensor but runs out of the sensor.
The sensor can also be bought with mounting bracket included, see article number 49337.
