gost standard Type N thermocouple wire
WISDOM type N Introduction:
Nicrosil-Nisil (Type N) thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. Type N thermocouple also be used in the similar atmospheres that type K works
Type N thermocouple improves the EMF drift and short term EMF change, compared to type K thermocouple, and has a longer life than type K thermocouple. Therefore, in the industries where temperature control and measurement are especially critical, type N thermocouple has more advantages than other thermocouple as it has long life and stable thermal EMF.
Type N chemical composition:
positive leg Nicrosil(NP) is Ni: Cr: Si≈84.4: 14.2: 1.4; negative leg Nisil (NN) is Ni: Si: Mg≈95.5: 4.4: 0.1
Type N Temperature Range:
· Thermocouple grade wire, -200~1300ºC(for short term) and 0~1100ºC( for long term)
· Extension wire, 32 to 392F (0 to 200C)
Type N Accuracy :
· Standard: +/- 2.2C or +/- .75%
