An Engine Monitor is only as good as its probes. That’s why Electronics International (EI) has taken the development of its probes, connectors, and accessories very seriously. EI has been designing and manufacturing probes for over 30 years. All of our probes have been designed in-house by our engineering team. Our team has studied, tested and designed temperature probes since the 1970′s. They have written research documents such as The Pilots Manual – Leaning and Diagnosing Engine Problems and Accurate CHT Measurements.
Just as an Engine Monitor is only as good as its probes, a probe is only as good as its connector. That’s why EI’s engineering team developed EI’s proprietary OLC-1 connector. The OLC-1 connector greatly increases reliability and reduces installation errors as compared to traditional type connectors. Whether you’re looking for a reliable and accurate CHT, EGT, TIT or various other probe types, EI has what you need. With more than a half million probes sold and tested you can count on EI’s reliability.
The C-2 kit includes two (2) P-100 CHT Probes.

Great customer support. My A&P installed a CGR in a Comanche and liked it.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
Your company shares a good reputation!
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Easy install, good product. [I chose EI because of my] experience with [the] product.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Good to go! Excellent instructions and easy install. Outstanding instrument!
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Installation went great. The Fuel Flow is dead on.
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
The equipment is fantastic, very intuitive, and easy to use.
