Coil Cord Thermocouple Wire

 

This section presents the most commonly used insulated thermocouple and thermocouple extension wire available from stock in all the ANSI recognized calibrations. All thermocouple and thermocouple extension wires are supplied to meet Standard Tolerances of ANSI Circular MC96.1-1982. Special tolerances to ANSI MC96.1 are available at an extra charge.

Color-Coding
Standard ANSI color-coding is used on all industrial thermocouple wire and extension wire when type of insulation permits. In color-coding, the right is reserved to include a tracer to identify the ANSI Type.
