Class One 1.29mm KP KN Thermocouple Wire Solid Wire IEC Standard ISO9001
IEC Standard Class One 1.29mm KP KN Thermocouple Wire With Oxidized Surface
Quick Description
A typical thermocouple construction consists of a pair of dissimilar metals that are electrically joined together at the sensing point and connected to a voltage measuring instrument at the other end. When one junction is hotter than the other, a thermal “electromotive” force (in millivolts) is produced that is roughly proportional to the difference in temperature between the hot and cold junctions.
Tankii Brand Type K thermocouple has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:
(1) Alternatively oxidizing and reducing atmosphere.
(2) Atmosphere with sulphur gases.
(3) Long time in vacuum.
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.
