Temperature Calibration

Temperature calibration refers to the calibration of any device used in a system that measures temperature. Most importantly, this usually means the temperature sensor, itself, which is typically a platinum resistance thermometer (PRT or PT-100), thermistor, or thermocouple.

Readings from these thermometers are made by “thermometer readout” devices which measure their electrical outputs and convert them to temperature according to the International Temperature Scale of 1990 (ITS-90).

Thermometers are typically calibrated by placing them in a stable temperature environment (heat source) and comparing their output to that of a calibrated “reference thermometer” or “standard thermometer.” Three general categories of heat sources include industrial heat sources (dry-well calibrators, Micro-Baths, etc.) for field use; fluid baths and thermocouple furnaces for laboratory use; and fixed-point cells for “primary” calibrations.

    Calibration of IR Thermometer

     

    Figure shows an example of an IR calibrator as a reference standard and an IR thermometer as a Unit Under Test (UUT). IR thermometers are equipment that measure temperature by using electromagnetic radiation. IR Thermometers are one of the most widely used instruments in industrial field.

    For calibration of IR Thermometers, to give confidence in measurement standards used shall be better than the IR Thermometer accuracy. Calibration is according to ASTM E1256:95. Calibration is conducted by measuring the reading based on distance, spot size and value of emissivity. The spot size diameter is approximately 1 inch. We cover calibration of IR Thermometer from -15°C to 500°C.

    Only competent technicians are authorized to carry out calibration work. Before the calibration process start, we will inspect and clean the instrument as in our procedure for calibration. During the calibration, the environment will be controlled as stated in our procedure. The concept for measurement is using direct measurement which is setting the value on a reference standard and comparing with the IR Thermometer reading.

    All safety precautions will be taken into account before, during and after calibration. In case any instrument is out of manufacturer’s specification, we will immediately notify our customer to get actual specification requirements. 

     

     

    Calibration of Temperature Enclosures

    Figure above shows examples of Paperless Temperature Recorder as a standard equipment and oven as a Unit Under Test (UUT). Temperature enclosure includes in oven, furnace, chiller, freezer and etc. Temperature enclosure measured for established the basic temperature performance characteristic of temperature enclosures for use throughout industry. Usually, temperature enclosures are used in heavy industries, welding and the food industry.

    Temperature enclosure calibration is important to ensure that equipment performs well. In calibration, we calibrate the enclosure equipment for linearity performance, stability variation, temporal variation and overall variation. We also do this calibration in accordance to AS 2853: 1986. We use calibrated standard equipment to calibrate the unit under test.

    Only competent technicians are authorized to carry out calibration work. Before the calibration process start, we will inspect and clean the instrument as in our procedure for calibration. 

    All safety precautions will be taken into account before, during and after calibration. In case if any instrument is having problem such as error is too high, malfunction, and so on, we will immediately inform our customer to advice.
