Active electrode Classic – RF-T 28 EL

The RF-T 28 active electrode is a probe for measuring humidity and air temperature and enables measurements to be taken in seconds.

  • The fast response speed of the sensor enables the detection of 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 surrounding climate can be compensated for
  • The BL-EL telescopic extension makes it possible to reach places that are difficult to access
  • 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 for
  • 90 % of the humidity difference approx. 20 sec and for
  • 95 % of the humidity difference approx. 30 sec
  • A filter cap made of sintered metal (stainless steel) can be used for measurements in dusty air, with pollutant emissions or high air velocity
