Humidity / frost and dew points

Contact Instrument Solutions

The Instrument Solutions humidity laboratory is equipped with a number of environmental chambers monitored with chilled mirror systems which gives the facility the capability of offering excellent levels of Calibration and Measurement Capability (CMC) Expressed as an Expanded Uncertainty.

Calibration options include traceable to national standards under the Instrument Solutions ISO 9001 accreditation or UKAS accredited calibrations against the ISO 17025 standard.

Humidity / dew and frost points chamber range:

  • 2 to 98 %rh over the range of 0 to 60 oC
  • 10 to 90 %rh over the range of 60 to 70 oC
  • -26 to -5 oC frost point
  • -8 to +60 oC dew point

All calibrations are conducted at standard calibration points, or as previous, unless instructed overwise.  Custom calibrations available, dependent upon calibration capabilities and instrument ranges.  Additional surcharge may apply.   

Typical standard calibration points 11.3, 45.3 and 75.3 % all at 25 oC.

For details of the laboratories ISO 17025 accredited scope for humidity parameters please refer to the UKAS Calibration Schedule on the link below.  Chamber ranges vary for different instrument designs (probes, loggers or chilled mirrors) please contact the calibration team on 01344 459314 or to discuss you technical requirements.
