1This simple thermocouple normally works with and display instruments, recording instruments and electronic regulators as a temperature sensor. 2It can directly measure solid surface temperature ranging from 0 to 400 of all kinds of production process. 3The thermocouple has small size, fast thermal response, with extension cable that can be bent arbitrarily. 4The structure is simple and it is convenient to use. 5Widely used for plastics, machinery, textiles, food industry, etc.
