Calibration of moisture meters


Accurate, reliable moisture measurement is important in many environments. A steady stream of moisture meters pass through our calibration lab all the time. For these calibrations we use several huminators (humidity chambers), the Thunder humidity generator, a calibration box and a fixed resistance calibration plate.


  • Accredited calibration according to ISO 17025
  • Lab and field calibration
  • Measuring range 1: 5 … 95 %RH at +15 … +40 °C.
    (both lab and field)
  • Measurement range 2: 10 … 95 %RH at 0 … +70 °C
    (only in labs – high accuracy)

In cooperation with several partners, we offer calibration of measuring points also in other ranges.

Humidity sensor in the Thunder cabinet


We accept most types of moisture measuring instruments, data loggers, transmitters and pressure dew point meters and issue a wide range of calibration certificates.

Testo Industrial Services


Together with Testo Industrial Services (TIS) we can also issue special proofs and certificates, for example in extreme areas or with a measurement uncertainty down to only 0.2 %RH. Please contact us for more information and prices on these calibration services.
