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.

Great… price [&] support
Very happy with our new tachometer!
Fantastic customer support!
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
The tach looks and operates amazing. Extremely accurate.
I have seen your products in other aircraft and have seen their reliability.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Outstanding Customer Service!!
