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.

[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
The tach looks and operates amazing. Extremely accurate.
[I chose EI because of its] Reputation and value.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
Great service. [I replaced/upgraded] unit in aircraft.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
Outstanding Customer Service!!
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
