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.

Compact, precise, awesome!
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
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.
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.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
We liked the price and the reputation of your company.
Very impressed with the clarity and readability of the CGR-30P gauge.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Excellent installation instructions [&] recommend[ed] by others.
Awesome Product! Great product and fantastic support!
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Customer support is great (and the) user interface is superior to other products.
