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.

Simple and Easy.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
Great tech support. Someone always answers and gives accurate concise information.
I really enjoy your products [because they are] simple and easy to use and affordable.
Good product; company is eager & willing to help
Great system and great benefit having everything in one place. Love it.
Good engineering support.
The reviews online were very good. Customer service has been great.
Your customer support is far superior . . . . I appreciate all your help.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], 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.
