The areas covered iron Kang Tong thermocouple measuring temperature of -200~1200 DEG C temperature range, but usually used for the 0 ~750 C
Thermocouple good degree of linearity, thermoelectric large, high sensitivity, stability and uniformity is good, the advantages of cheap, widely used by users. The type J thermocouple can be used in vacuum, oxidation, reduction and inert atmosphere, but positive iron oxidation at high temperatures is fast, so use temperature is limited, can not no direct protection at high temperatures for curing atmosphere.
