Thermometer Calibration Using Controlled Temperature Baths

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.

Thermometer calibration using controlled temperature baths.

They offer unsurpassed stability and uniformity a large working volume and flexibility for performing thermometer calibration or calibrating a variety of temperature sensors. The sensor is usually a composite material containing metallic oxides. A comparison from a known zero value the ice bath. Place crushed ice in a beaker or container add just enough distilled water to make a uniform slush ice.

To make sure your thermometer is accurate it must be calibrated and that s where ice bath temperature comes in. To calibrate a thermometer for low temperature monitoring follow these steps. If you need more accuracy at a higher range it is advisable to send your ir thermometer to a qualified calibration lab. 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.

The resistance change is not generally as stable with time as the rtd sensors. August 1999 2 3 2 thermistor thermistor is the electrical resistance of the sensor varies with its temperature. Below you ll find five easy steps for calibrating your food thermometer using an ice bath. 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.

Ideal for monitoring temperatures in refrigerators freezers water baths heating blocks. You might be asking how do you calibrate a thermometer with ice water. How to perform calibration of ir thermometer using the ice bath. Calibration baths fluke calibration baths provide optimal temperature environments for secondary or comparison temperature calibrations.

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. This low cost water bath is ideal for checking the calibration of a wide range of instrumentation including thermometers and data loggers. This is a simple calibration procedure designed to calibrate your ir thermometer at the zero deg c range only. Tex 926 k construction division 2 7 effective date.

Thermometer calibration using controlled temperature baths txdot designation. High temperature calibration can be used for low temperature calibration as long as the thermometer is allowed to equilibrate to room temperature before use.
