Instructions for Moisture Measurement in Building Materials on the Basis of
the Measurement of the Relative Air Humidity
using the active electrodes RF-T 31 and RF-T 36
Set selector switch (3) (UNI 1) or (4) (UNI 2) to position »M«.
Connect selected active electrode to the meter socket (1) (UNI 1) or (2) (UNI 2).
Press measuring key (4) (UNI 1) or (5) (UNI 2) and read off result displayed (in % R.H.) by the LCD
readout (2) (UNI 1) or (3) (UNI 2).
Technical specifications
Measuring range: 5 to 98 % R.H. for short periods.
For continuous or long period measurements in
the range above 80 % R.H., a special calibra-
tion is required for the measuring sensors.
Admissible operating temperature -10 °C to +60 °C f or short periods,
for the meter and the electrodes: 0 °C to +50 °C for long periods.
Admissible ambient conditions
for the storage of the meter -10 °C to +60 °C for short periods
and the electrodes: 5 °C to +40 °C for long per iods.
5 % to 98 % R.H. for short periods *)
35 % to 70 % R.H. for long periods *)
