Questions
Thermocouple Wire / Extension Wire calibration FAQ
How often should a thermocouple wire / extension wire be calibrated?
Thermocouple wires used as permanent reference sensors should be calibrated every 12 months.
Is thermocouple wire / extension wire calibration accredited?
Yes. Thermocouple Wire / Extension Wire calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering types S, R, J, K, N, T and E, with cold-junction calibration at 0 °C to 30 °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 thermocouple wire / extension wire 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 thermocouple wire / extension wire?
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.
