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.

Customer Testimonials

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, 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.

CGR-30P Premium Engine Monitor

I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

Installation went great. The Fuel Flow is dead on.

The R-1-6 is a great instrument. [I chose EI because of] quality.

J. Gregg from North Carolina

R-1 RPM Tachometer Instrument

Great service. [I replaced/upgraded] unit in aircraft.

Adam M. from NSW, Australia

Piper PA-28-181 Cherokee

VA-1A Volts/Amps Instrument

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.

David K. from New Mexico

Cessna T20N Turbo Centurion II

R-1 RPM Tachometer Instrument

The reviews online were very good. Customer service has been great.

Jason H. from Arizona

Cessna 172 Skyhawk

FP-5L Fuel Computer

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.

Casey R. from Oklahoma

OPT-1 Oil Pressure and Temp Instrument

Great tech support. Someone always answers and gives accurate concise information.
