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.

Gauge works great! Very happy with purchase.
Pleasure supporting folks with like values.
I really enjoy your products [because they are] simple and easy to use and affordable.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
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.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, 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.
The tach looks and operates amazing. Extremely accurate.
We have other EI products currently and have always been satisfied.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
