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 product and good product support!
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Excellent Service. Superb Product.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
We liked the price and the reputation of your company.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
