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.

Excellent installation instructions [&] recommend[ed] by others.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
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!
Pleasure supporting folks with like values.
Your products always work great! Great customer service and a quality product that we have used for years.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
The quality and design appear to be excellent.
