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.

Your (customer) service is excellent!
Excellent Service, superb product.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
[I chose EI because of its] Reputation and value.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
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.
[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.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Nice bright display.
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
