Platinum rhodium thermocouple calibration range and uncertainty analysis

NPL for the use of zinc, silver and bronze ( As much as 1100 & deg; C) The freezing point and the melting point of gold and palladium ( As much as 1600 & deg; C) The platinum rhodium thermocouple with UKAS certification thermocouple calibration services ( Lab no. 0478) 。 In addition, including platinum melting point calibration can provide certificate of NPL ( As much as 1800 & deg; C) 。

NPL platinum - also provide calibration Rhodium thermocouple, the thermocouple by internal building and calibration can provide any of the following options. These are made of assemble insulators wires. Wire diameter of 0. 5 mm, length is 2 m, thermocouple can purchase, with or without the cold end is connected to the copper extension cord.

thermocouples are widely used in industry, temperature measurement and control for many applications. They are popular because they are small and strong, suitable for use in a very high temperature and relatively low cost. They also provide convenient electrical output for data record and control. Platinum - Rhodium thermocouple ( R, S and B) Available to other base metals thermocouple calibration standard and high temperature applications.

use the new metal carbon fixed point calibration

- as high temperature metal Carbon eutectic fixed point of the result of the extensive research and development, NPL now offers and/or calibration with UKAS certificate R, S and B type thermocouple service, significantly reduces the uncertainty of the measurement.

this uncertainty by using cobalt - Carbon eutectic fixed point ( 1324℃） Or palladium - Carbon eutectic fixed point ( 1492℃） The highest temperature of the fixed point calibration. Compared with line bridge fixed point, the Co - C and Pd - C fixed point has low inherent uncertainty.

for more information on the most advanced protection, please see the eutectic fixed point of the page, the fixed point has been recently introduced into the NPL calibration plan.

range and uncertainty R, S and B type thermocouple calibration uncertainty ( Coverage of about 95%) :

* B type thermocouple calibration & from 400 deg; C

__ Calibration point is melting or cells using freezing point, unless otherwise specified, Wb = wire bridge method)
