Thermometer calibration using controlled temperature baths.

How to perform calibration of ir thermometer using the ice bath. Below you ll find five easy steps for calibrating your food thermometer using an ice bath. 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. 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.

They offer unsurpassed stability and uniformity a large working volume and flexibility for performing thermometer calibration or calibrating a variety of temperature sensors. To calibrate a thermometer for low temperature monitoring follow these steps. Place crushed ice in a beaker or container add just enough distilled water to make a uniform slush ice. High temperature calibration can be used for low temperature calibration as long as the thermometer is allowed to equilibrate to room temperature before use.

Calibration baths fluke calibration baths provide optimal temperature environments for secondary or comparison temperature calibrations. You might be asking how do you calibrate a thermometer with ice water. 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. If you need more accuracy at a higher range it is advisable to send your ir thermometer to a qualified calibration lab.

This is a simple calibration procedure designed to calibrate your ir thermometer at the zero deg c range only. Thermometer calibration temperature calibration. The resistance change is not generally as stable with time as the rtd 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.

August 1999 2 3 2 thermistor thermistor is the electrical resistance of the sensor varies with its temperature. 1 1 requirements as a general rule temperature measurement and control devices must periodically be. Tex 926 k construction division 2 7 effective date. The sensor is usually a composite material containing metallic oxides.

A comparison from a known zero value the ice bath. To make sure your thermometer is accurate it must be calibrated and that s where ice bath temperature comes in.
