Product Description

TPX TNX Copper Constantan Theremocpuple Extension Bare Wire 100ºC Class 1 Accuracy

 

TYPE T (Copper vs Constantan) is used or service in oxidizing, inert or reducing atmospheres or in vacuum. It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures. It is the only type with limits of error guaranteed for cryogenic temperatures.
