Classification, temperature measurement range, accuracy, advantages and disadvantages of thermocouples

Thermocouple type	Temperature measurement range	IGrade accuracy	IIGrade accuracy	Advantages/Disadvantages
Ktype	-200~+1300℃	±1.5℃	±2.5℃	Cheap price, widely applicable, suitable for use in oxidizing and inert atmospheres/Bare wire is not suitable for use in vacuum, carbon containing, sulfur-containing, and redox alternating atmospheres; The stability of high-temperature thermoelectric potential is not as good as that of N-type.
Jtype	-200~+950℃	±1.5℃	±2.5℃	Cheap price, higher thermoelectric potential than K-type, can be used in both oxidizing and reducing atmospheres, resistant to H2 and CO corrosion/cannot be used in sulfur-containing atmospheres. After exceeding 538 ℃, the iron electrode oxidizes quickly, and its temperature resistance is not high enough, making it unsuitable for use in high-temperature areas
Etype	-200~+850℃	±1.5℃	±2.5℃	Cheap price, maximum thermoelectric potential, high sensitivity/insufficient temperature resistance, no high temperature zone The method uses other characteristics similar to the K-type
Ntype	-200~+1300℃	±1.5℃	±2.5℃	Cheap price, strong high-temperature oxidation resistance, nuclear radiation resistance, ultra-low temperature resistance, good long-term stability of thermoelectric potential rate/small thermoelectric potential rate, relatively late introduction compared to other types, not widely used
Ttype	-200~+350℃	±0.5℃	±1.0℃	Cheap price, high precision/poor oxidation resistance, not resistant to high temperatures
S/Rtype	-200~+1600℃	±1.0℃	±1.5℃	Resistant to ultra-high temperatures, suitable for use in oxidizing and inert atmospheres/expensive, with extremely low thermoelectric potential at room temperature, not suitable for measurement at medium and low temperatures
Btype	-200~+1800℃	---	±4.0℃	Resistant to ultra-high temperatures, suitable for use in oxidizing or neutral atmospheres/expensive, with extremely low thermoelectric potential at room temperature, not suitable for measurement at medium and low temperatures
