CHT probe (left) is a high quality Chrome / Constantan "E" type. A more expensive material than the more commonly found "J" type, the "E" type probe produces much greater accuracy at lower temps. (less than 600°F). Extension wire is the same material as the thermocouple to preserve the accuracy and temp. compensation qualities. NOTE: 15 extension leads may be shortened up to 7 ft. EGT probes are high quality Chrome/Alumel K types. Choose the weld-on boss type (center) for new engine installations. Choose the clamp-on type (right) to replace the existing probe. Order gauges, Micro-1000 probes, and extensions separately.

Note: These are "K" type grounded probes, not for use on digital gauges. For use with Micro-1000 gauges.
