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.

Straight up install no issues. Works as advertised!
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
I have worked with your products before and I like them.
Well documented installation process and Support was helpful.
I really enjoy your products [because they are] simple and easy to use and affordable.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
EI has the best customer service of any company that I’ve ever dealt with.
Great product and excellent customer service!
All looks very nice. [I chose E.I. because of] previous experience.
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.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
