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.

Your (customer) service is excellent!
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
Nice product and good product support!
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
Your products always work great! Great customer service and a quality product that we have used for years.
Easy installation.
Nice unit. EI is the best!
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
