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.

Customer support is great (and the) user interface is superior to other products.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Good to go! Excellent instructions and easy install. Outstanding instrument!
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
EI tech support is the best.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
. . . looks really good! Friends have these installed and give very good reviews.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
