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.

I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
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.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
The R-1-6 is a great instrument. [I chose EI because of] quality.
Incredible customer service.
Great products and very clear install.
Your sales and support teams are very helpful.
EI tech support is the best.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
