Product Overview

Type T thermocouple bare wire consists of uninsulated copper (positive) and constantan (negative) conductors designed for direct temperature sensing in non-corrosive environments. This high-accuracy solution is ideal for laboratory testing, cryogenic applications, and custom sensor assemblies where insulation isn't required.

Standard Designations
  • Thermocouple Type: T-type (Copper-Constantan)
  • IEC Standard: IEC 60584-1
  • ANSI Standard: ANSI MC96.1
  • Color Coding: Positive (blue), Negative (red) per IEC standards
Key Features
  • Direct thermal contact with measured objects via uninsulated design
  • High accuracy across -200°C to 350°C range
  • Exceptional stability in cryogenic environments
  • Low electrical resistance minimizes signal loss
  • Compatible with standard T-type connectors
