Overview

The AERO 353 has a built-in state-of-the art CO sensor that immediately reacts to the presence of CO. It was designed for pilots who want the unit to be small, so it takes up a minimum of panel space, and provides pilots a peace of mind.

Detector will go into alarm mode within five minutes if CO level is greater than 50 PPM.

The unit has dual light LED alarm; Amber less than 99 PPM and Red 100 PPM and above.
Very simple installation (2-4 hours).

Great product except the thread for the supplied mounting screws (in the unit body) was badly over sized, actually to the point that the supplied screws would not tighten. Put the next size screw in after taping out and that fixed the problem, but you then have 2 screw heads that are bigger than the rest of the pannel but no biggy can live with that
