Accredited ranges
Energy Logger / Power 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
Energy Logger / Power Meter calibration FAQ
How often should a energy logger / power meter be calibrated?
Energy loggers and power meters should be calibrated every 12 months, or before any energy audit or carbon emissions reporting cycle.
Is energy logger / power meter calibration accredited?
Yes. Energy Logger / Power Meter calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering DC and AC power 0.02 W to 1500 kW. 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 energy logger / power 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.
Which brands of energy logger / power meter do you calibrate?
Commonly submitted brands include Fluke and Yokogawa. 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.
