DMMs that can measure temperature typically use which adapter?

Digital Multimeters (DMMs) that have the capability to measure temperature often utilize a thermocouple as an adapter. This is because thermocouples are widely used for temperature measurement due to their broad temperature range and quick response time. They operate based on the principle that when two different metals are joined at one end and heated at that joint, they produce a voltage corresponding to the temperature difference between the joint and the other ends of the metals. This voltage can be interpreted by the DMM to provide an accurate temperature reading.

Thermocouples are favored in various applications for their durability and the ability to withstand extreme temperatures, which makes them particularly useful in automotive diagnostics for monitoring engine temperature, among other uses. Their reliability and ease of integration with DMMs make them the preferred choice for temperature measurement in this context.
