Accredited ranges
Temperature Data Logger 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
Temperature Data Logger calibration FAQ
How often should a temperature data logger be calibrated?
Temperature data loggers should be calibrated every 12 months, or before any IQ/OQ/PQ validation exercise.
Is temperature data logger calibration accredited?
Yes. Temperature Data Logger calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering thermocouple inputs from -250 °C to 1770 °C (type-dependent) and PT385 RTD inputs from -200 °C to 800 °C. 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 temperature data logger 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.
Which brands of temperature data logger do you calibrate?
Commonly submitted brands include Fluke. This list covers the models customers most often send in, not our full capability — send us your make and model and we'll confirm whether it falls within our accredited scope or can be calibrated as a traceable service.
