Temperature Calibration

Calibration by comparison performed within either a dry block calibrator or an isothermal block within a temperature-controlled enclosure.  

Accuracy

Temperature sensor calibration is carried out in four essential stages: preparation, temperature stabilisation, measurement, and reporting.

We use two systems depending on the calibration range required. A dry block calibrator uses an electrically heated metal block with wells of varying diameters to accommodate different probes, covering a range of 0 °C to 100 °C. A temperature controlled chamber maintains a stable, uniform environment in which the probe is placed, with a calibration range of 5 °C to 50 °C.

    UKAS Calibration Service in the range 0 °C to 100 °C with an uncertainty of 0.16 °C.

    The complete calibration procedure for a temperature sensor consists of four essential stages. Preperation, temperature stabilization, measurement and reporting.  

    Two different sytems are used for temperature calibrations; dry block calibrator or the temperature controlled chamber.  

     Dry block calibrator uses an electrically heated metal block with wells of different diameters to accommodate the probes. Calibration range using this system is 0 °C to 100 °C. 

     Temperature controlled oven maintains a stable, uniform temperature chamber in which the probe is placed. Calibration range using this system is 5 °C to 50 °C.
