Type B  thermocouple

B-type thermocouple in the series, with the highest accuracy and stability of the best, wide-temperature-zone, long life, high temperature limit. Applicable to oxidation and inert atmosphere can also be used for short-term vacuum, but does not apply to restore an atmosphere of or containing metal or non-metallic vapor in the atmosphere. B-type thermocouple is a clear advantage is not required for the purposes of compensation lead to compensate, as in 0 ~ 50 °C within the framework of thermal power less than3μV.

Application

It is widely used in high temperature production process such as glass, ceramic industry and industrial NaCl bathing stove, etc.
