Thermometer Calibration Using Controlled Temperature Baths

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.

Thermometer calibration using controlled temperature baths.

High temperature calibration can be used for low temperature calibration as long as the thermometer is allowed to equilibrate to room temperature before use. You might be asking how do you calibrate a thermometer with ice water. 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. Ideal for monitoring temperatures in refrigerators freezers water baths heating blocks.

August 1999 2 3 2 thermistor thermistor is the electrical resistance of the sensor varies with its temperature. Thermometer calibration temperature calibration. How to perform calibration of ir thermometer using the ice bath. This is a simple calibration procedure designed to calibrate your ir thermometer at the zero deg c range only.

A comparison from a known zero value the ice bath. 1 1 requirements as a general rule temperature measurement and control devices must periodically be. The sensor is usually a composite material containing metallic oxides. This low cost water bath is ideal for checking the calibration of a wide range of instrumentation including thermometers and data loggers.

Calibration baths fluke calibration baths provide optimal temperature environments for secondary or comparison temperature calibrations. The resistance change is not generally as stable with time as the rtd sensors. At pcs we provide a wide range of iso 17025 accredited calibration services for all types of thermometers and temperature control systems used in ovens furnaces kilns freezers and other temperature controlled applications. Thermometer calibration using controlled temperature baths txdot designation.

High accuracy thermometer has a temperature range of 58 to 158 f 50 to 70 c and resolution of 0 01 and maintains an accuracy of 0 25 c across the entire temperature range. They offer unsurpassed stability and uniformity a large working volume and flexibility for performing thermometer calibration or calibrating a variety of temperature sensors. If you need more accuracy at a higher range it is advisable to send your ir thermometer to a qualified calibration lab. To calibrate a thermometer for low temperature monitoring follow these steps.

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. Place crushed ice in a beaker or container add just enough distilled water to make a uniform slush ice.
