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.

Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Big improvement over old cluster (gauges). Good customer service.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
Good product; company is eager & willing to help
Nice bright display.
Excellent Service. Superb Product.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
