Questions
Platinum Resistance Thermometer (PRT) calibration FAQ
How often should a platinum resistance thermometer (PRT) be calibrated?
PRTs used as working standards should be calibrated every 12 months, or whenever repaired or suspected of damage.
Is platinum resistance thermometer (PRT) calibration accredited?
Yes. Platinum Resistance Thermometer (PRT) calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering -95 °C to 660 °C, plus fixed points from -196 °C to 660.3226 °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 platinum resistance thermometer (PRT) 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 platinum resistance thermometer (PRT)?
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.
