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 service. [I replaced/upgraded] unit in aircraft.
Safety and simplicity!
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Great product. So easy to read compared to the originals.
Works Great!
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Nice unit. EI is the best!
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
[Customer service] is great!
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
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!
