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.

Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
We have other EI products currently and have always been satisfied.
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.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Excellent Service. Superb Product.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
The tach looks and operates amazing. Extremely accurate.
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
MVP-50 is a really great product
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
