Accurate Humidity Measurements
Accredited calibration humidity meters, performed both in our laboratory and on-site at your premises.
Our accredited laboratory provides calibration of a wide range of measuring instruments of relative humidity of air (hygrometers). Calibrations are performed using reference standards and measurement systems with demonstrated metrological traceability. For each calibrated item, we issue a calibration certificate in accordance with ISO/IEC 17025. Results are accurate, reproducible, and internationally recognized under ISO/IEC 17025. Calibrations are carried out in our laboratory or within the accredited scope on site at the customer’s premises.
We calibrate the following instruments
Accredited:
- Relative humidity meters (capacitive, hair, transducers)
- Hygrographs
- Relative humidity and temperature recorders
Special Capability:
- Accredited to perform humidity calibrations on-site at customer facilities

Note:
The scope of accreditation, together with the associated uncertainties, is provided in the appendix. Upon agreement and within our technical capabilities, we can calibrate beyond the accredited scope as non-accredited measurements. In such cases, we provide proof of traceability to internationally recognized SI units.

Frequently Asked Questions
Can calibrations be performed at my premises?
Which humidity measurement devices can you calibrate?
We calibrate capacitive and hair hygrometers, transducers, hygrographs, and combined temperature-humidity recorders.
How often should humidity instruments be calibrated?
Annual calibration is common, but critical applications or regulatory requirements may require more frequent checks.
