Product Overview
A-1 OAT Overview
OAT or Carb Temp
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.
Ice Zone Warning
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.
Reliable Probes
A-1 OAT Kit Includes:
- One (1) P-110F Fast Response EGT Probe
- One (1) P-100 CHT Probe
- One (1) P-128 OAT/Carb Probe
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.

Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Best sales team.
