Thermocouple Bare Wire Type K Nicr Nisi Kp Kn

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: Sia 84.4: 14.2: 1.4; negative leg Nisil (NN) is Ni: Si: Mga 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 -200~1300a . 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. High quality with high measuring accuracy, fast thermal response, high mechanical strength, long service lifetime, wide temp measuring range of -200-1300 centigrade .
