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.
