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 E-1 kit includes one (1) P-110F Fast Response EGT Probe.

Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Safety and simplicity!
Great product at a great price …. (and) reliability.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Awesome Product! Great product and fantastic support!
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Great customer support. My A&P installed a CGR in a Comanche and liked it.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Good equipment at a good price. I have used your products before and have had great success.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
