EGT probe sheath material is Inconel which is extremely corrosion resistant and is made for high temperatures. The inner core cables are teflon(ptfe) insulated which is less prone to shorting and corrosion because it does not absorb moisture compared to fibreglass insulation. The probe has a  1200msecond response time and comes with a stainless steel braided cable and 1/8 compression fitting. We can also make custom made EGT sensors to your specifications. Can fit special connector lugs to fit your gauge. Spade lugs, ring lugs, fork lugs, bullet connectors and k type mini connector. Made in Australia.
