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.

Why did you choose our products over the competition? Complete kit and ease of installation.
Simple and Easy.
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.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
People [at EI] were great to work with.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Very pleased with the quality. [Chose because of] positive reviews from other aircraft owners.
Love my new engine monitoring system.
We have other EI products currently and have always been satisfied.
I really enjoy your products [because they are] simple and easy to use and affordable.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
