⚫ Type J 24 Ga. TC Grade Wire
This Type J thermocouple-grade wire uses 24 AWG solid Iron (+) and Constantan (-) conductors with FEP insulation rated to 400°F (204°C). It is designed for fabricating Type J thermocouples and carrying temperature signals directly from the sensing junction.
The white Iron (+) conductor is magnetic, helping identify polarity during installation. Standard accuracy is ±4°F (±2°C) per ASTM standards, with a recommended maximum signal distance of approximately 110 ft without amplification.

Detailed Specifications For Extension Wire
Use with compatible Type J thermocouple circuits and instrumentation. Verify polarity, insulation limits, installation environment, and required signal distance before use. Protect the Iron (+) conductor from moisture where practical to reduce oxidation and corrosion. Where documented measurement validation is required, annual calibration of the complete temperature measurement system is important for confirming continued accuracy and proper operation.
