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-1 connector. The OLC-1 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.
The E-1 kit includes one (1) P-110F Fast Response EGT Probe.

Works Great!
I really enjoy your products [because they are] simple and easy to use and affordable.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Very happy with our new tachometer!
Easy Install.
Fantastic customer support!
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Simple and Easy.
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
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!
