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.

Met all my requirements; great support.
Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.
Works Great! Love it!
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Excellent tech help…
The tach looks and operates amazing. Extremely accurate.
People [at EI] were great to work with.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
Works great!
Excellent customer service. Without a doubt the best aviation part I have purchased.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Great Service.
