UKAS Accredited Calibration Laboratory
|
The calibration laboratory of Rotronic Instruments UK Limited is UKAS accredited for the calibration of humidity and temperature measuring instruments. Our calibration service offers competitive pricing and a typical turnaround time of 72 hours for a three point relative humidity calibration.
Services we offer 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 0 °C to 70 °C temperature range
Calibration of dew-point measuring instruments over the range -25 °C dew point to +70 °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 70 °C; 10 %rh to 98 %rh
Temperature calibration of probes in air 0 °C to 70 °C
Temperature calibration of probes in liquid -10 °C to 125 °C

Calibration Devices
These are small, airtight containers which fit exactly onto the respective sensor and form an airtight enclosure around the sensor. The lower screw-on part is then filled with the humidity standard material. The desired humidity level is reached following a settling period of typically 60 minutes at a constant temperature. The equipment can now be adjusted to match the reference humidity value. We offer suitable devices for every ROTRONIC sensor and can also construct an appropriate calibration device for your humidity measurement equipment.
