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 equipment is fantastic, very intuitive, and easy to use.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
Awesome product. Fast easy installation.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Very impressed with the clarity and readability of the CGR-30P gauge.
. . . looks really good! Friends have these installed and give very good reviews.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
[Customer service] is great!
So far, great product
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.
