The thermocouple is a commonly used temperature-measuring instrument. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The basic structure of thermocouples is roughly the same, usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes and junction boxes, and used in conjunction with display instruments, recording instruments and electronic regulators.

Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives, or small pieces of metal in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive surface allows easy handling. Superior to ring sensor hand probes. Ultra-high sensitivity, special application. Such as prisons, chip factories, archaeological research hospitals, etc. Handheld metal detectors are used to detect the specific location of metal carried by a person.
