How to implement fixed-point of thermocouple calibration service

Thermocouple calibration laboratory calibration the following types of thermocouple: basic metal

specified in the letter, E、J、K, N, T)

specifies the letters ( W / Re,红外/ Rh, Pt / Rh)

precious metals ( 年代,R, B)

pure metals ( Au / Pt，Pt / Pd）

all common types of thermocouple calibration services by NIST in - 196° C to + 2100 & deg; C within the scope of supply. Specific calibration temperature range depends on the wire or the type of thermocouple.

thermocouple 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 Pt - maintain platinum thermoelectric reference standards 67 test thermocouple single leg.

the 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 calibration type E, type J, K, N, T, S, 70 / B

W is 80 cm/Re is 100 cm

- point calibration

100 cm for base metal thermocouple ( E, J, K, N, T) And thermocouple material, can only accept unused thermocouple test. Only when the thermocouple could meet the precision calibration.

how to arrange the calibration:

if you have any technical or calibration cost problem, please contact the staff responsible for artifact calibration services.

calibration according to the principle of first come first served.

use a copy of the purchase order delivery of your artifacts. Using strong boxes, in which we can return to the calibration instrument.

you can via email, fax or email will be sent the E-mail to contact the purchase order. Please include the following information:
