Thermometer Calibration Using Controlled Temperature Baths

To make sure your thermometer is accurate it must be calibrated and that s where ice bath temperature comes in.

Thermometer calibration using controlled temperature baths.

The resistance change is not generally as stable with time as the rtd sensors. Platinum resistance thermometers prts standard platinum resistance thermometers sprts and liquid in glass thermometers can all be calibrated through the use of a temperature bath with longer thermometers a deep well compact constant temperature bath can be used for calibration. High temperature calibration can be used for low temperature calibration as long as the thermometer is allowed to equilibrate to room temperature before use. Place crushed ice in a beaker or container add just enough distilled water to make a uniform slush ice.

If you need more accuracy at a higher range it is advisable to send your ir thermometer to a qualified calibration lab. They offer unsurpassed stability and uniformity a large working volume and flexibility for performing thermometer calibration or calibrating a variety of temperature sensors. Switch the water bath on set the verification temperature and insert your temperature probe into the bath and compare the results against your reference thermometer it could not be easier. Calibration baths fluke calibration baths provide optimal temperature environments for secondary or comparison temperature calibrations.

The sensor is usually a composite material containing metallic oxides. 1 1 requirements as a general rule temperature measurement and control devices must periodically be. This low cost water bath is ideal for checking the calibration of a wide range of instrumentation including thermometers and data loggers. August 1999 2 3 2 thermistor thermistor is the electrical resistance of the sensor varies with its temperature.

How to perform calibration of ir thermometer using the ice bath. To calibrate temperature monitoring and temperature control devices in the absence of a nationally or internationally accredited calibration laboratory using the ice water procedure and it outlines the limitations of this approach. You might be asking how do you calibrate a thermometer with ice water. To calibrate a thermometer for low temperature monitoring follow these steps.
