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.

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.

E.I. Always Exceeds Expectations!
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
EI’s products are the only ones we recommend to our customers.
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Your (customer) service is excellent!
Great customer service!
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
