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.

Customer Service is far superior… with an excellent record of resolving … technical issues.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
The layout and quality is impressive.
Great Service.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
Great… price [&] support
Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Incredible customer service.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
