Polyimide T2 Thermocouple Insulated Wire (Ni95/(Al+Mn+Si) 5)

Polyimide T2 Thermocouple Insulated Wire (Ni95/(Al+Mn+Si) 5) is a product from Goodfellow that contains 77 variations of insulated wire made from thermocouple alloys and polyimide insulation. The polyimide provides high heat and chemical resistance while the thermocouple alloys enable accurate temperature measurement. This wire can be used in a wide range of industrial and scientific applications requiring precise temperature monitoring in high temperature environments, such as automotive testing, chemical processing, and aerospace systems. The availability of numerous alloy combinations allows selection of the optimal wire for a given temperature range and environment.
