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-1 kit includes one (1) P-110F Fast Response EGT Probe.

Awesome Product! Great product and fantastic support!
Easy installation.
EI’s team is great; you guys are the best.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Beautiful graphic display, easy to use, perfect automatic dimming!
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
[I chose EI because of its] Reputation and value.
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 like how the kits ship with everything needed for install and the wire labeling was very helpful.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
