Accredited ranges
Freezer / Chiller / Cold Room 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
Freezer / Chiller / Cold Room calibration FAQ
How often should a freezer / chiller / cold room be calibrated?
Pharmaceutical and medical cold storage should be calibrated every 12 months or after any significant maintenance, breakdown or relocation event.
Is freezer / chiller / cold room calibration accredited?
Yes. Freezer / Chiller / Cold Room calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering -80 °C to 50 °C (within our temperature enclosure scope). 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 freezer / chiller / cold room 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 freezer / chiller / cold room?
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.
