The second-class standard platinum rhodium 30 platinum rhodium 6 thermocouple (B-type thermocouple) has the advantages of high accuracy, good stability, wide temperature measurement range, long service life, and high temperature measurement upper limit in the thermocouple series.
Suitable for oxidizing and inert atmospheres, and can also be used in vacuum for a short period of time, but not suitable for reducing atmospheres or atmospheres containing metal (non-metal) vapor. One obvious advantage of B-type thermocouples is that the reference end does not require compensation wires.
The electrode diameter of the new standard B-type thermocouple is 0.5-0.015mm, and the measuring points are welded smoothly, upright, and shiny. The length of the thermocouple shall not be less than 1000mm.

Including the metrology certificate of the National Defense Science and Technology Industry First Metrology Testing and Research Center, the technical indicators meet the requirements of current regulations/specifications.
