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.

Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
Phone service for ordering was quick and easy. Shipping was quick.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
Great product, frees up space
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Your products always work great! Great customer service and a quality product that we have used for years.
The layout and quality is impressive.
The R-1-6 is a great instrument. [I chose EI because of] quality.
You folks do a great job. Keep up the good work.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
The tach looks and operates amazing. Extremely accurate.
