1.b type thermocouple 2.temp.0 to 1800C 3.aluminum ceramic tube sheathed 4.stem dia:8 to 25mm 5.connection:flange or screw 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 than3uV. Application It is widely used in high temperature production process such as glass, ceramic industry and industrial NaCl bathing stove, etc. Models WRR-130 WRR2-130 B 0-1800 Corundum tube <150S 16 WRR-131 WRR2-131 <360S 25 stem specification:L x l(mm) 300x150 350x200 400x250 450x300 550x400 650x500 900x750 1150x1000 1650x1500 2150x2000
