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.

Sharp-looking gauges. [I chose EI because of your] reputation.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Great service. [I replaced/upgraded] unit in aircraft.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
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.
Easy Install.
Love it!
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
