The active electorde RF-T28 is a standard sensor used for the measurement of air temperature and air humidity and allows measurements within seconds.
The electrode can be used together with the Hydromettes M 4050, RTU 600, UNI 1 and UNI 2.
The sensor has the ability to respond quickly and therefore can be used to detect all kinds of leaks, e.g. doorcracks or untight windows, due the the fact that even low air flows influence the measured values
The sensor is able to adapt to the ambient conditions even if it is turned off
In order to obtain very precise measurements the device should have an adaptation period of approx. 10 - 15 minutes to compensate temperature differences
Measuring range of the RF-T 28: 7 - 98 % RH and -10° - +80° C
The response timefor the air humidity sensor (low air flow, ambient conditions: 20° - 25° C) is
approx. 20 seconds for 90 % of the respective difference in relative humidity and
approx. 30 seconds for 95 % of the respective difference in relative humidity
If measuring in dust containing air, pollutant emissions or high air speed a filter cap made of sinter bronze can be used
