TP TN 0.1mm Copper Type T Thermocouple Extension Wire
Product Overview
Type T Thermocouple extension wire (TP--Copper, TN--Cu-Ni), also known as Cu-Constantan thermocouple, offers exceptional stability for extremely low temperature applications including cryogenics and ultra low freezers. This wire is widely used in laboratory environments and industrial temperature measurement systems.
Key Features:
- Excellent repeatability between –200°C to 200°C (–380°F to 392°F)
- Manufactured according to GB/T 4990-2010 (Chinese National Standard) and IEC584-3 (International standard)
- Used in temperature measurement instruments and process control systems
- Conductors match the thermo-electric (emf) properties of thermocouples
