CO Guardian Aero 551

AERO 551 is designed to fit a standard 2 1/4 panel hole. This unit is our most sophisticated CO detector; it produces an extremely fast response when carbon monoxide is present.

The CO display page in the AERO 551 shows the CO level in ppm ( Parts per million ). The AERO-551 can display CO from 10 ppm to 999 ppm. (For any level above 999 PPM, the display will register only 999). The alarm will sound within 5 minutes if the CO level stays above 75 +/- 5 ppm. If the CO level rises above 300 ppm, the alarm will trigger within one minute.
