How can multimeter measure temperature?

[akinokoe]

The multimeter in our lab has temperature measurement function. I am wondering how it works. Can it measure temperature of insulating materials or it just work for metal?

You connect a thermocouple. Temperature is then a millivolt measurement with a scaling factor

A multimeter can measure temperature by using a thermocouple or a thermistor. These are electronic components that change their electrical resistance in response to temperature changes. The multimeter measures this change in resistance and converts it into a temperature reading.

The type of material being measured does not affect the temperature measurement as long as the thermocouple or thermistor is in contact with the material. This means that the multimeter can measure temperature for both metal and insulating materials.

However, it is important to note that the accuracy and range of the temperature measurement may differ depending on the type of material being measured. For example, a thermocouple may have a wider temperature range and better accuracy when measuring metal compared to insulating materials.

Overall, a multimeter with a temperature measurement function can be a useful tool for measuring temperature in a laboratory setting. It is important to ensure that the appropriate type of thermocouple or thermistor is used for the material being measured in order to obtain accurate results.
