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-2 connector. The OLC-2 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.

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Straight up install no issues. Works as advertised!
I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Good to go! Excellent instructions and easy install. Outstanding instrument!
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
EI tech support is the best.
Your (customer) service is excellent!
