Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

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.

Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Amazing aftermarket service. Good quality products
Great product. So easy to read compared to the originals.
Works great!
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
Great product at a great price …. (and) reliability.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
EI’s team is great; you guys are the best.
Your customer support is far superior . . . . I appreciate all your help.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
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.
Why did you choose our products over the competition? Complete kit and ease of installation.
