What is temperature probe calibration?

Temperature probe calibration is the process of comparing the measurements of a certain temperature probe, such as a thermistor, RTD or thermocouple, to a reference device to establish the accuracy of the temperature probe.

Any measurement deviances of the device to be calibrated are adjusted to the parameters of the reference device. The aim of calibrating temperature probe instruments is to maximize accuracy and thus reliability in temperature readings.

Calibration schemes are not only relevant in terms of product quality and safety, but also regarding compliance. Industry standards, such as the Good Distribution Practice (GDP) for pharmaceutical manufacturers, often require the use of only calibrated sensors for storing and transporting goods.

Probes Unlimited provides comprehensive calibration services for their custom precision temperature sensors.

Their calibration lab can offer calibration NIST certificates from -40-400 degrees centigrade. We can also provide volume sorting capabilities for tight tolerance requirements.

Temperature calibration can be accomplished in a variety of ways and with various degrees of accuracy. As with any calibration, a standard must be used. The standards used in temperature calibration can come in different forms but must be certified with an accuracy that is traceable to a national standard – NIST.

In industrial applications, temperature calibration usually involves thermistors or thermocouples. These are devices used to accurately measure temperature. Readings from these devices can be compared with less accurate field temperature sensors and used to evaluate the viability of those devices or to perform a temperature calibration.

Many manufacturing processes use heat to modify product characteristics. In some cases, precise temperature control is essential to ensure fitness for purpose and a paper trail (temperature logs plus evidence of calibration) verifies the manufacturer took appropriate steps to maintain the quality of the items produced. Calibration of temperature sensors is an essential part of this activity.

Temperature sensors monitor the most common quality metric in the manufacturing industry: temperature. These temperature measurement devices play a key role in ensuring temperature conditions are constantly kept at an optimal level during production, storage, and transportation of temperature-sensitive goods. Regular calibration of temperature sensors ensures the long-term accuracy of measurements and eventually, product quality and safety.
