We now offer the CO-USB Carbon Monoxide Alarm that flips the orientation of the LEDs so that panel installations can be better accommodated, while retaining the features of the CO-USB Original. However, it does not have the digital output port.
CO-USB-UP provides a brilliant and reliable indication of CO poisoning. Per FAA guidelines, it flashes bright RED at 41 PPM. For reference, see Carbon Monoxide, a Deadly Menace (faa.gov).
It features a breakthrough electrochemical sensor that provides excellent anti-interference from other gases.
It's part of our commitment to prioritize affordability, ease of use, simplicity, and reliability—all crucial features for enhancing safety in aviation.
