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.

Great Service.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Your customer support is far superior . . . . I appreciate all your help.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Your products always work great! Great customer service and a quality product that we have used for years.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Good engineering support.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
The equipment is fantastic, very intuitive, and easy to use.
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.
