Product Description Thermocouple Compensation Cable Type K NiCr-Nickel Si (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. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It 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.
