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.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
This is the second product purchased and I am completely satisfied.
My mechanic said that your product was very good, and he was correct.
EI’s products are the only ones we recommend to our customers.
Great product and excellent customer service!
Works great!
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.
Your company shares a good reputation!
Good to go! Excellent instructions and easy install. Outstanding instrument!
Very pleased with the quality. [Chose because of] positive reviews from other aircraft owners.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
