Product Description

Product Description

As a sensor for measuring temperature, thermocouples are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the temperature of liquid, steam and gas media in various production processes ranging from 0ºC to 1800ºC.

Features

1. High quality temperature sensing elements, stable and reliable performance
2. High mechanical strength and good pressure resistance
3. Large measuring range and high measuring accuracy
