Temperature Measurement Bench has been designed for students to study different types of temperature measurement methods. This is a complete, freestanding apparatus to demonstrate fundamental temperature measuring techniques using thermocouples, mercury in glass thermometer, resistance temperature detector (RTD), thermistor, bimetallic temperature indicator and etc.

Temperature measurement is used to measure air temperature, boiling water temperature, ice-point temperature and wet or dry bulb temperature. Temperature can be measured via a various ranges of sensors. All of these sensors infer temperature by sensing changes in physical characteristics. Thermocouples consist essentially of two wires made of different metals that joined at one end.

Resistance temperature detector devices capitalize on the fact that the electrical resistance of a metal changes as a result of temperature change. Thermistors are based on resistance change in ceramic semiconductor where the resistance drops nonlinearly with temperature rise. Bimetallic devices take advantage of the difference in rate of thermal expansion between different metals.
