PST Dew Point Calibration Services

PST have calibration laboratories offering Dew Point calibrations in 8 locations across the globe. Of these, three are ISO17025 accredited:

Michell Instruments UK

The calibration laboratory of Michell Instruments is UKAS accredited for the measurement of humidity and dew point. Michell Instruments has been the pioneer in humidity and dewpoint calibrations opening the first humidity calibration lab in UK. Today it offers a calibration service for most moisture sensors and instrumentation, carried out against test equipment traceable to NPL (National Physical Laboratory, London, UK) and NIST (National Institute of Standards & Technology, Maryland, USA) through Michell’s ISO/IEC 17025 UKAS (United Kingdom Accreditation Service) accreditation.

Dew point calibration services include

  • Traceable ISO9001 calibration from -100 to +90°C (-148 to +194°F) dew point
  • ISO/IEC 17025 (UKAS) accredited calibrations from -90 to +90°C (-130 to +194°F) dew point

Schedule of Accreditation

Michell Japan

Michell Japan gained accreditation to Japan Calibration Services System (JCSS) in May 2013. The laboratory is accredited for -70 to -10 °C dew-point calibration, via an S4000TRS reference chilled mirror which is directly traceable to the National Institute of Advanced Industrial Science and Technology (AIST).

Dew point calibration services include

  • Traceable ISO9001 calibration from -100 to +20 °C (-148 to +68 °F) dew point
  • ISO/IEC 17025 (JCSS) accredited calibrations from -70 to -10 °C (-94 to +14 °F) dew point

Rotronic UK

The UKAS laboratory at Rotronic UK has steadily evolved over the last few years increasing confidence in the calibrations performed and consequently lowering the Calibration and Measurement Capability (CMC) of the laboratory. Now offering dew point calibration in a wide range from a few PPM towards the boiling point of water.

Dew point calibration services include

  • ISO/IEC 17025 accredited calibrations from -60 to +95°C (-76 to +203°F) dew point

Schedule of Accreditation

Which Calibration Do I Need?
Factory Adjustment Certificate (ISO) OR SCS/UKAS Certificate?

SCS, UKAS and JCSS-Certificate Calibrations

Your internal quality process requirements generally determine whether a factory adjustment certificate suffices or whether an ISO 17025 (SCS/UKAS) certificate is needed. SCS or UKAS certificates are generally required in the pharmaceutical industry, the medical technology industry, research and development and the food industry. ISO 17025 certifications are performed with high precision reference hygrometers and for temperature calibration, an equally high precision temperature bath is used. The best possible SCS or UKAS calibration uncertainty can only be achieved if all factors which could influence the result are controlled and checked at the highest level – SCS or UKAS certification is therefore only possible in one of our accredited laboratories.

Factory Calibrations as per ISO 9001 Standard

A standard traceable adjustment certification in accordance with ISO9001 can be carried out by you, or by our calibration technicians. Traceable calibrations in our laboratories will be carried out using a Michell Instruments dew-point generator and chilled mirror reference with an accredited calibration.

Process Sensing Technologies offer a wide range of products to facilitate dew point calibrations on-site.

NVLAP
Our UKAS accreditation is commonly recognised elsewhere in the world as EAL, or NVLAP (National Voluntary Laboratory Accreditation Program) in the USA.
