The active electrode RF-T 28 is a probe for air humidity and air temperature measurement and enables measurements within seconds.
The electrode can be used with the hydromettes M 4050, Gann Hydromette RTU 600, #30001670UNI 1 und UNI 2.
The sensor's fast response speed makes it possible to detect leaks, e.g. door gaps or leaking windows, as even slight air currents influence the measured value display.
The sensor adapts to the ambient climate even when switched off
For particularly precise measurements, the device should be exposed to the ambient climate to be measured for 10 - 15 minutes so that any temperature differences between the electrode and the ambient climate can be compensated.
The telescopic extension BL-EL (order no. 6040) makes it possible to reach places that are difficult to access (see photo on the left).
Measuring range of the RF-T 28: 7 - 98 % r.h. and -10 - +80 °C
The response time of the humidity sensor (slightly moving air, ambient temperature: 20 - 25 °C) is about 20 sec for90 % of the humidity difference and about 30 sec for 95 % of the humidity difference
For measurements in dusty air, pollutant emission or high air velocity, a filter cap made of sintered metal (stainless steel) can be used
Compatible with the following Gann measuring instruments:
