PST have calibration laboratories offering Relative Humidity calibrations in six locations across the globe. Of these, four are ISO 17025 accredited:
Rotronic Switzerland
The high-precision calibration of temperature and humidity measuring devices accordingly places high demands on the reference device.
Our accredited ISO 17025 calibration laboratory (SCS 0065) offers the highest, traceable accuracy for your measurements in the areas of temperature and relative humidity
Calibrations are possible for Rotronic and third-party products!
The measuring ranges and the measurement uncertainties can be found here:
- SCS directory - calibration and measurement options (CMC)
- SCS accreditation - certificate
- Order form SCS calibration
- GXP services - calibration ISO 9001 & ISO 17025 (SCS)
Services include
- Calibration of relative humidity measuring instruments over the range 0.5 %rh to 99 %rh at 23 °C ±2 °C
- Calibration of relative humidity measuring instruments over the range 10 %rh to 95 %rh, from -10 °C to +70 °C
- Calibration of temperature probes in air from -10 °C to +70 °C
- Calibration of temperature probes in liquid from -25 °C to +125 °C
- On site at the customer in Switzerland, humidity from 10 %rh to 90 %rh at 10 °C to 40 °C
- On site at the customer in Switzerland, temperature in dry block calibrator from -90 °C to 125 °C
PST/Rotronic UK
ISO 17025 accredited calibration of humidity and temperature sensors validates performance and is increasingly a requirement of industry regulations and corporate quality management systems. Rotronic UKAS laboratory has continued to develop over recent years, increasing confidence in the calibrations performed and consequently improving the measurement uncertainty in the laboratory's Calibration and Measurement Capability (CMC). The measurement methods for dew point and temperature in air have been significantly improved, which in turn has affected the relative humidity (rh) calibrations.
Services include
- Calibration of relative humidity measuring instruments using unsaturated salt solutions at 5 %rh, 10 %rh, 11 %rh, 20 %rh, 35 %rh, 50 %rh, 65 %rh, 75 %rh, 80 %rh & 95 %rh over a range 23 °C ±2 °C
- Calibration of dew point measuring instruments over the range -60 °C dew point to +95 °C dew point
- Calibration of relative humidity measuring instruments by comparison with a chilled mirror hygrometer and platinum resistance thermometers in the range 0 °C to 95 °C; 2 %rh to 98 %rh
- Temperature calibration of probes in air -60 °C to 150 °C
- Temperature calibration of probes in liquid -70 °C to 200 °C
- Full Accreditation Scope
PST/Rotronic Germany
The highly accurate calibration of temperature & humidity meters requires the highest requirements for the reference device.
Our accredited ISO 17025 calibration laboratory at Rotronic Germany (SCS 0065) offers the highest traceable accuracy for its measurement in the areas of temperature and relative humidity.
Calibration is possible for Rotronic products as well as for third-party products!
