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-1 connector. The OLC-1 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 E-2 kit includes two (2) P-110F Fast Response EGT Probes.

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

Well documented installation process and Support was helpful.
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.
