Also known as: RTD Resistance Thermometer · PT100 Sensor · Resistance Temperature Detector
Why calibrate?
Unitest calibrates RTDs (resistance temperature detectors) and PT100/PT385 sensors in Singapore over a range of -95°C to 660°C, with SAC-SINGLAS accredited ISO/IEC 17025 certificates. RTD resistance shifts gradually with repeated thermal cycling, mechanical stress and contamination; calibration confirms the resistance-temperature relationship is still accurate and the traceability chain is intact for process control and regulatory submissions.

Questions
RTD / PT100 Temperature Sensor calibration FAQ
How often should a RTD / PT100 temperature sensor be calibrated?
RTDs are typically calibrated every 12 months. Critical pharmaceutical or food-safety applications should follow a 6-monthly schedule.
Is RTD / PT100 temperature sensor calibration accredited?
Yes. RTD / PT100 Temperature Sensor calibration is covered under our SAC-SINGLAS scope of accreditation (LA-2023-0845-C, ISO/IEC 17025), covering -95 °C to 660 °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 RTD / PT100 temperature sensor 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 RTD / PT100 temperature sensor?
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.
