Thermocouple fixed point calibration service how to execute the - Shanghai dragon instrument electric appliance co. , LTD

Thermocouple calibration laboratory calibration the following types of thermocouple: basic metal specified in the letter, E, J, K, N, T) Specify the letters ( W/Re,Ir/Rh,Pt/Rh) Precious metals ( 年代,R, B) Pure metals ( 非盟/ Pt, Pt / Pd) All common types of thermocouple calibration services by NIST in - Within the scope of 196 ° c to + 2100 ° c. Specific calibration temperature range depends on the wire or the type of thermocouple. Thermocouple is by comparing or fixed point calibration, depending on thermocouple type and temperature range and the desired accuracy. Both methods can be traced back to 1990, the international scale ( 它的, 90). 。 The comparison of thermocouple wire thermocouple calibration used in NIST maintenance reference. Use ITS - thermocouple fixed point calibration 90 the four definitions of temperature: zinc, aluminum, silver and gold freezing point. By the first or the second approach, aiming at NIST P t - maintain platinum thermoelectric reference standards 67 test thermocouple single leg. NIST thermocouple calibration need only bare wire. We hope that customers don't send ceramic insulation and protection tube, because they may be damaged during the transit. If the installation of the thermocouple protection tube components such as the transportation, may be special remove the charge, and under the condition of parts will be assembled in return. Submit calibration of thermocouple wire minimum length should be at least as follows: to compare the calibration model, J type, type, type, type and s type, 70 type B type is 80 cm w/Re as fixed-point calibration - 100 cm 100 cm for the base metal thermocouple ( E, J, k, N) and type And thermocouple material, can only accept unused thermocouple test. Only when the thermocouple could meet the precision calibration. How to arrange the calibration:
