Electrical Calibration
Unitest provides SAC-SINGLAS accredited electrical calibration in Singapore for digital multimeters, clamp meters, insulation testers, calibrators, power meters and process instruments, with traceable ISO/IEC 17025 certificates, in our lab or on-site. Calibration compares each instrument against a known reference standard so its readings stay accurate, keeping your work safe and audit-ready..
View electrical calibration →Temperature Calibration
Unitest provides SAC-SINGLAS accredited contact temperature calibration in Singapore over a range of -196°C to 1000°C (for thermocouples, RTDs, thermistors, thermometers, temperature data loggers, dry-blocks, baths and furnaces), with traceable ISO/IEC 17025 certificates, in-lab or on-site. Calibration compares your instrument against a reference standard of known accuracy so deviations can be identified and corrected..
View temperature calibration →Non-Contact Temperature (IR) Calibration
Unitest calibrates non-contact infrared thermometers and thermal imagers in Singapore over a range of 35°C to 500°C, against a traceable reference source, with ISO/IEC 17025 certificates. Non-contact instruments measure temperature from a distance using infrared radiation (ideal for hazardous, moving or hard-to-reach surfaces), so calibration verifies their readings match the true temperature..

Unitest provides fixed-point temperature calibration in Singapore for high-accuracy reference thermometry, traceable to ISO/IEC 17025 and tied to the International Temperature Scale of 1990 (ITS-90). We use fixed-point cells, including liquid nitrogen (≈ -196.0°C), the triple point of water (0.01°C), gallium (29.7647°C) and aluminium (660.3226°C). Whose precisely defined phase transitions deliver the lowest measurement uncertainty..
View fixed-point temperature calibration →Humidity Calibration
Unitest provides humidity calibration in Singapore over a range of 5% to 90% relative humidity (at temperatures of 5°C to 50°C) (for hygrometers, humidity/temperature probes and data loggers, transmitters and climatic chambers), with traceable ISO/IEC 17025 certificates. Calibration stabilises the sample gas and measures it against a more accurate reference instrument..
View humidity calibration →Pressure Calibration
Unitest provides SAC-SINGLAS accredited pressure calibration in Singapore over a range of -14.5 psi to 10,000 psi (for pressure gauges, transmitters, transducers, switches and vacuum instruments), with traceable ISO/IEC 17025 certificates, at our lab or on-site. We use methods such as a hydraulic deadweight tester or pressure balance against certified reference gauges..
View pressure calibration →Oscilloscope Calibration
Unitest calibrates oscilloscopes in Singapore for bandwidth up to 1100 MHz (verifying bandwidth, timebase, amplitude and trigger accuracy against known reference standards), with traceable ISO/IEC 17025 certificates, in our lab or on-site..
View oscilloscope calibration →Chamber & Freezer Calibration
Unitest calibrates and maps environmental chambers, ovens, fridges and freezers in Singapore over a temperature range of -80°C to 1000°C (assessing temperature (and humidity) uniformity and stability), with traceable ISO/IEC 17025 certificates, on-site. Accurate, stable temperatures are critical for R&D, pharmaceuticals, cold storage and manufacturing..
View chamber & freezer calibration →Weighing Scale & Balance Calibration
Unitest calibrates weighing scales and balances in Singapore up to 5 kg as a traceable (non-accredited) calibration service, from basic digital scales to high-performance load-cell models, including analytical, precision, bench and platform scales. Using traceable reference weights, in our lab or on-site for fixed scales. Weighing scale calibration is not part of our SAC-SINGLAS accredited scope; certificates are issued as traceable calibration, which suits most internal quality and process uses and keeps weights, counts and totals accurate..
View weighing scale & balance calibration →Tachometer Calibration
Unitest calibrates contact, non-contact, laser and optical tachometers and RPM meters in Singapore with traceable ISO/IEC 17025 certificates. A tachometer measures the rotational speed of machinery, so accurate readings are essential for keeping equipment running well and safely..
View tachometer calibration →Timer & Stopwatch Calibration
Unitest calibrates digital and mechanical timers and stopwatches in Singapore against a traceable time/frequency reference, with ISO/IEC 17025 certificates. Timing can drift over time through ageing mechanisms, battery fluctuations or mechanical wear, so calibration keeps your elapsed-time measurements reliable..
View timer & stopwatch calibration →Liquid Bath Calibration
Unitest characterises and calibrates liquid temperature baths in Singapore. Verifying and adjusting temperature accuracy against certified reference standards, and assessing stability and uniformity, with traceable ISO/IEC 17025 certificates. Over time, fluid degradation, sensor drift and controller wear can affect a bath's performance, so regular calibration keeps it reliable for testing and calibration work..
View liquid bath calibration →RTD Probe Calibration
Unitest provides SAC-SINGLAS accredited RTD probe calibration in Singapore from -80 C to 660 C in the lab (and -95 C to 660 C on-site), with lab measurement uncertainties (CMC) from 0.01 C to 0.39 C under method UNI-T001, and traceable ISO/IEC 17025 certificates. We calibrate industrial resistance temperature detectors, including Pt100 and Pt1000 process and lab RTDs, by comparison against reference standards of known accuracy, so any drift in the probe's reading is found, measured and reported, keeping your process temperatures audit-ready..
View rtd probe calibration →PRT Probe Calibration
Unitest provides SAC-SINGLAS accredited PRT probe calibration in Singapore from -80 C to 660 C in the lab (and -95 C to 660 C on-site), with lab measurement uncertainties (CMC) from 0.01 C to 0.39 C under method UNI-T001, and traceable ISO/IEC 17025 certificates. We calibrate reference-grade platinum resistance thermometers, including standard platinum resistance thermometers (SPRTs) and reference PRTs used as temperature standards, against references of known accuracy so your laboratory's temperature reference stays trustworthy and audit-ready..
View prt probe calibration →Thermistor Calibration
Unitest calibrates thermistor probes (including NTC and PTC types) in Singapore as a traceable calibration, by comparison against accredited reference thermometers, and issues an ISO/IEC 17025 traceable certificate. Thermistor calibration is not separately named on our SAC-SINGLAS accredited schedule (which lists RTD, PRT and thermocouple sensors), so we do not describe the thermistor calibration itself as accredited. Instead we calibrate your thermistor against reference standards whose own traceability is accredited under LA-2023-0845-C. Contact us to confirm the scope for your specific sensor..
