Product Description
Nicrosil-Nisil (Type N) thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of 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 thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is -200~1300℃.
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 Accuracy :
Standard: +/- 1.5 ℃ or +/-0.4%t (GB)
+/- 1.1 ℃ or +/-0.4%t (ANSI E 230 Limits of Error)
+/- 2.2 ℃ or +/-0.75%t (ANSI E 230 Standard)
