Electronics International’s A-1 instrument provides pilots with the precision and stability needed in order to accurately monitor Outside Air Temperature or Carburetor Temperature while in-flight.
Not only will Electronics International’s A-1 display Outside Air Temp with a stable, one-degree (Fahrenheit) resolution, it also comes complete with an “Ice Zone” light that alerts the pilot when the Outside Air Temperature could possibly contribute to ice forming in the aircraft carburetor.
A 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 a 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.

Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
