Product Description

NiCr-Ni (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500 °C.

Type K thermocouple has strong resistance to oxidation than other base metal thermocouples.
Type K thermocouple has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost.
Type K thermocouple is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:

(1) Alternatively oxidizing and reducing atmosphere.
(2) Atmosphere with sulphur gases.
(3) Long time in vacuum.
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.

Thermocouple extension grade wire, such as  KX, EX, NX, TX, JX can be used for thermocouple cable, usually with second class EMF tolerance and cheaper price.
