Why calibrate?
Unitest calibrates dew point meters and chilled mirror hygrometers in Singapore using our SAC-SINGLAS accredited humidity calibration service (40% to 90% RH), with traceable ISO/IEC 17025 certificates. Chilled mirror sensors accumulate contamination over time; polymer-film dew point sensors drift with exposure to solvents or very dry air. Calibration against our Michell S8000 dew-point reference confirms the reading is accurate for compressed gas quality, pharmaceutical manufacturing and corrosion prevention.

How often
How often should a dew point meter be calibrated?
Dew point meters should be calibrated every 12 months. Critical compressed air or gas drying systems may warrant 6-monthly calibration.
Accredited ranges
Dew Point Meter calibration ranges & measurement uncertainty
The parameters, ranges and calibration & measurement capability (CMC) below are taken from our SAC-SINGLAS Schedule of Accreditation (LA-2023-0845-C, to ISO/IEC 17025). CMC is the smallest measurement uncertainty we can achieve under accredited conditions.

Questions
Dew Point Meter calibration FAQ
How often should a dew point meter be calibrated?
Dew point meters should be calibrated every 12 months. Critical compressed air or gas drying systems may warrant 6-monthly calibration.
Is dew point meter calibration accredited?
Yes. Dew Point Meter calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering 40% to 90% RH (chilled-mirror reference). Certificates state the measured values and measurement uncertainty, traceable to national and international standards. Where an instrument falls outside the accredited ranges, we can calibrate it as a traceable service instead.
How long does dew point meter calibration take?
Standard turnaround is 5 to 7 working days; express service is 2 to 3 working days. Collection and delivery in Singapore are free for orders above $300.
Can you calibrate my brand of dew point meter?
Almost certainly — the makes listed on this site are simply the ones customers most commonly send in. Send us the make and model and our engineers will confirm whether it falls within our accredited scope or can be calibrated as a traceable service.
