Thermocouple Extension Cable Guideline

Type Code	Positive Leg	Negative Leg	Recommended Temp. Range	Colour Code (ANSI MC96.1)	APPLICATION INFORMATION
J	Iron ThermoKanthal JP*	Constantan Cupron Advance* ThermoKanthal JN*	0 to 760 ^oC (32 to 1400 F)	Jacket: Black + White -Red	Suitable for Vacuum, reducing/ inert atmospheres. Life reduced in oxidizing atmosphere. Do not expose bare conductor to Sulphurous atmosphere. Only heavy gauge wire for higher temperature
K	Chromel* Tophel* T1* ThermoKanthal KP* Isotherm Plus*	Alumel* Nial* T2* ThermoKanthal KN* Isotherm Minus*	0 to 1200 ^oC (32 to 2300 F)	Jacket: Yellow + Yellow -Red	Suitable for continuous oxidizing and inert atmosphere. Good above 1000 F. Subject to Failure if exposed to Sulphur. Proper ventilation or sealing is preferred.
T	Copper	Constantan Cupron Advance*	-184 to 371 ^oC (-300 to 7000 F)	Jacket: Blue + Blue -Red	Recommended for all type of atmospheres i.e. oxidizing, reducing & inert and in vacuum. Limits of error to be borne in mind.
E	Chromel* Tophel* T1* ThermoKanthal KP*	Constantan Cupron Advance* ThermoKanthal JN*	0 to 871 ^oC (32 to 1600 F)	Jacket: Purple + Purple -Red	Suitable for continuous oxidizing and inert atmosphere. Highest thermoelectric output of common calibration.
N	-Nicrosil* -14.5% Chromium +1.4% Silicon +0.1% Magnesium + Balance Nickel	-Nisil* -4.2% Silicon +0.1% Magnesium + Balance Nickel	0 to 1260 ^oC (32 to 2300 F)	Jacket: Orange + Orange -Red	Can be used in applications where Type K elements have shorter life.
