How often
How often should a differential pressure instrument be calibrated?
Differential pressure instruments should be calibrated every 12 months, or before any cleanroom validation or commissioning exercise.
Accredited ranges
Differential Pressure Instrument 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
Differential Pressure Instrument calibration FAQ
How often should a differential pressure instrument be calibrated?
Differential pressure instruments should be calibrated every 12 months, or before any cleanroom validation or commissioning exercise.
Is differential pressure instrument calibration accredited?
Yes. Differential Pressure Instrument calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering -13 psi to 1000 psi (pneumatic). 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 differential pressure instrument 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 differential pressure instrument?
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.
