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.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
The R-1-6 is a great instrument. [I chose EI because of] quality.
While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
Incredible customer service.
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 chose EI because they offer a] certified replacement vs. back-up only and they look great.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Beautiful graphic display, easy to use, perfect automatic dimming!
EI tech support is the best.
Nice product and good product support!
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
