Temperature Calibration Services in Singapore

What is Contact Temperature Calibration?

Contact temperature calibration is a systematic procedure used to verify and adjust the accuracy of temperature measuring instruments that come into direct physical contact with the object or medium being measured. These instruments can include thermocouples, resistance temperature detectors (RTDs), thermistors, and various other temperature sensors. Calibration compares the readings of the instrument to a reference standard of known accuracy, allowing any deviations or inaccuracies to be identified and corrected. Unitest Instrument delivers professional temperature calibration services in Singapore.

When Should You Perform Contact Temperature Calibration?

The frequency of temperature calibration depends on various factors, including the type of instrument, its usage, and environmental conditions. As a general guideline:

New Instruments: New temperature measuring instruments should undergo initial calibration to establish their accuracy.

Regular Calibration: Periodic calibration is recommended, typically annually or based on the instrument’s specifications and industry standards.

Critical Applications: For applications where temperature accuracy is crucial, more frequent calibration may be necessary.

After Significant Events: Calibration should be performed after any significant event, such as mechanical shock, exposure to extreme temperatures, or repairs/modifications.


In conclusion, contact temperature calibration is a vital process for achieving accurate and reliable temperature measurements. Properly calibrated temperature measuring instruments are essential for process control, compliance, data confidence, and successful research and development. By understanding the importance of calibration and following the appropriate calibration procedures, you can ensure that your temperature measurements are of the highest quality.

Why is Temperature Calibration Important?


Accurate temperature measurements are critical in numerous industries and applications , such as manufacturing, pharmaceuticals, food processing, environmental monitoring, and scientific research. Here’s why contact temperature calibration is of utmost importance:

Process Control and Quality Assurance: In industrial settings, precise temperature control is vital for ensuring consistent product quality, process efficiency, and safety. Calibration ensures that the temperature measurements used for process control are reliable and accurate.

Compliance and Standards: Many industries must adhere to specific regulations and standards that require regular temperature calibration to maintain certification and compliance.

Data Confidence: Calibration instills confidence in the accuracy of temperature measurements, allowing you to make informed decisions based on trustworthy data.

Equipment Performance Verification: Calibration helps identify any drift or deviations in the performance of temperature sensors, allowing for timely maintenance and preventing costly breakdowns.

Research and Development: In scientific research, precise temperature measurements are essential for accurate experimentation and data analysis. Calibration ensures that research outcomes are valid and replicable.

Why is it necessary to calibrate a thermometer?


Thermometer accuracy can change over time, so you should calibrate your thermometer to ensure accurate readings.

Thermometers can drift over time for two reasons. First, mechanical shock can cause the thermometer to drift. Second, thermometers can drift when exposed to extreme temperatures.

What is calibrated with a temperature calibrator?


Common items calibrated with temperature calibrators include thermometers, thermocouples, thermistors, and temperature transmitters.
