工藝： 熱電偶是由兩個根不同的導體材質組成，讓測量端與參比端它們形成溫差就會產生熱電勢，工作儀表就會顯示出熱電勢所對應的溫度值。

    用途： 用于空氣、氣體、液體、以及固體表面的溫度測量。它與記錄儀表或與電子計算機配套使用。

    特點： 它能測不同介質的工作溫度（0-1300℃）。機械絕度高，耐壓性能好。

Technology: thermocouple root of the two different conductor material composition, measuring end-to-reference them with a temperature will result in thermoelectric power, the instrument will show thermoelectric potential value of the corresponding temperature.
Applications: Used in air, gases, liquids, solids and surface temperature measurement. It records and electronic instruments or the use of computer matching.
Features: It can test different medium temperature （0-1300 ℃）. Machinery must high pressure good performance.
