Product Overview

Reliable Probes

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.

Easy Install.

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.

Great service and support for great products!
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
I have other EI products and your support is great.
