Designed by pilots and RV builders to solve the problem every pilot knows about - unreliable and unintuitive CO detectors.
Most pilots believe that CO is only present in an emergency, but CO is present on every flight and changes between startup, runup, climb, cruise, and descent. This portable detector is designed to be sensitive and responsive at the lowest levels of CO gas between 0 and 255 ppm to detect and manage CO before it becomes an all-out emergency.
The Aithre Shield 4.0 auto-pairs to your iOS device using our free Aithre Connect app. Readings are collected in the background and Siri notifies you via your iOS-paired headset when 2ppm, 10ppm, and 50ppm are crossed. The app keeps 15 minutes of trend data so you don't need to look at it unless there is an issue. As a safety backup, the Aithre Shield 4.0 also has a glowing light indication of the CO levels and an alarm that is triggered at 50 ppm.
