PT100/PT1000:Three-wire system

Thermocouples support K, T, J, E, and N types.

Measuring range

NTC:-40℃~140℃;

PT100: the maximum support is - 200 ℃~850 ℃, and the actual range depends on PT100;

PT1000: the maximum support is - 200 ℃~850 ℃, and the actual range depends on PT1000;

Thermocouple: the maximum support is - 200 ℃~1372 ℃, and the actual range depends on the thermocouple model.
