Why calibrate?
Unitest calibrates digital temperature indicators in Singapore for thermocouple (Types K, J, T, N, R, S, E) and RTD (PT385/PT100) inputs over a range of -80°C to 660°C, with traceable ISO/IEC 17025 certificates. Temperature indicators convert a sensor signal into a readable value — drift in the input conversion circuitry means the display may show an incorrect temperature even when the probe itself is accurate. Calibration checks the indicator independently, keeping the full measurement chain traceable.

Questions
Digital Temperature Indicator calibration FAQ
How often should a digital temperature indicator be calibrated?
Temperature indicators should be calibrated every 12 months. Indicators in critical process control may need a 6-monthly interval.
Is digital temperature indicator calibration accredited?
Yes. Digital Temperature Indicator 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 digital temperature indicator 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 digital temperature indicator 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.
