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 EC-2 kit includes two (2) P-110F Fast Response EGT Probes and two (2) P-100 CHT Probes.

Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
So far, great product
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Keep it up. I’ll keep coming back.
My mechanic said that your product was very good, and he was correct.
Good engineering support.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
