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.

Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
You folks do a great job. Keep up the good work.
Works great!
Excellent Service, superb product.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
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.
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.
Fantastic customer support!
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.
Great product. [nothing else] can compete.
