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 service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Awesome product. Fast easy installation.
Good engineering support.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
