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.

Great product. [I chose EI because] you have no competition.
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.
Your products always work great! Great customer service and a quality product that we have used for years.
Installation went great. The Fuel Flow is dead on.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
E.I. Always Exceeds Expectations!
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Works Great! Love it!
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
Nice unit. EI is the best!
Fantastic customer support!
