10 Feet. 24 AWG Kapton®. Used for hot temperature. Each Type J thermocouple comes with a welded tip and connection end bared and ready to install.
May be used, protected or unprotected, where there is a deficiency of free oxygen, but, again for cleanliness and generally longer life, a protecting tube is recommended. Since JP (iron) wire will oxidize rapidly at temperatures over 1000°F ( 538°C), it is recommended that larger gauge wires be used to compensate. Maximum recommended operating temperature is 1400°F ( 760°C).
Tolerance at ±1.1°C or ±0.4%
Temperature Operating Range at 0°C to 750°C ( 32°F to 1382°F)
