2,Specifications of protection tube(total length and well length)

Temperature needed:0~1800C

Graduation S normally means: 0-1300°C
Graduation B normally means: 0-1600°C
Graduation R normally means: 1400-1500°C.Method of fixing: normally without fixing device, but flange or threaded is available.

3.SUM-UP :

B type thermocouple for you .such type the standard  wire diameter is 0.5mm,( s-positive pole) material is Platinum - 70%, Rhodium - 30% ;(s- negative pole) is Platinum – 94%, Rhodium – 6%, using temperature highest can reach 1600 degree.

WRR B type thermocouple

1) Strong junction box to enclose parts that might produce sparks,
    electric arc, and dangerous high temperatures
2) When explosions within the box occur, fire and high temperatures
    caused by explosion are extinguished and cooled within the gap
3) Various explosion-proof types are available
4) Good explosion proof performance
5) Spring thermal element with good shockproof performance
6) Wide measuring range
