1.measuring method is the expansion of two different metals
2.suitable for measuring on-site low-and-medium temperature

It can be used to measure the temperature of gases,liquids and  other substance. The indicating value can be readout on the spot, and can be transmitted to control room also.The transmitted signals include Pt100,K type & E type thermal resistance one, can also be converted become a 4-20mA DC standard signal.
