Thermometer Calibration Using Controlled Temperature Baths

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.

Thermometer calibration using controlled temperature baths.

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. If you need more accuracy at a higher range it is advisable to send your ir thermometer to a qualified calibration lab. Thermometer calibration using controlled temperature baths txdot designation. Calibration baths fluke calibration baths provide optimal temperature environments for secondary or comparison temperature calibrations.

August 1999 2 3 2 thermistor thermistor is the electrical resistance of the sensor varies with its temperature. To calibrate a thermometer for low temperature monitoring follow these steps. Ideal for monitoring temperatures in refrigerators freezers water baths heating blocks. Below you ll find five easy steps for calibrating your food thermometer using an ice bath.

Tex 926 k construction division 2 7 effective date. 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. The resistance change is not generally as stable with time as the rtd sensors. They offer unsurpassed stability and uniformity a large working volume and flexibility for performing thermometer calibration or calibrating a variety of temperature sensors.

This low cost water bath is ideal for checking the calibration of a wide range of instrumentation including thermometers and data loggers. A comparison from a known zero value the ice bath. Thermometer calibration temperature calibration. How to perform calibration of ir thermometer using the ice bath.

To make sure your thermometer is accurate it must be calibrated and that s where ice bath temperature comes in. Place crushed ice in a beaker or container add just enough distilled water to make a uniform slush ice. 1 1 requirements as a general rule temperature measurement and control devices must periodically be. This is a simple calibration procedure designed to calibrate your ir thermometer at the zero deg c range only.

High temperature calibration can be used for low temperature calibration as long as the thermometer is allowed to equilibrate to room temperature before use. 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.
