Color Coding on JEM/Martin Smoke Machine Thermocouples 

From November 2006, all thermocouple wire used in JEM and Martin smoke machines and spare part heat exchangers will be color-coded according to the European standard IEC 584-3. This means that the following color code now applies: 

Black +ve 

White -ve 

Thermocouples produced using the new color code will be labelled to identify wire color/polarity.
