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 have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Very impressed with the clarity and readability of the CGR-30P gauge.
Great product, frees up space
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
You folks do a great job. Keep up the good work.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
