Some of the novel temperature transducers which meet the thermal potential of thermocouples, e. g. the infrared temperature probe and compound armored thermocouple are introduced.

Thermocouples and thermopiles are devices that use the Seebeck effect to measure the temperature difference between two objects, one connected to a voltmeter and the other to the probe.

From the cooling curves of the change rules, we have put forward application the thermocuple silver-bulb probe method which is a new method of detection of the magnetic water.
