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!

Product Overview

Reliable Probes

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.

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.

I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
