The Airspace AI-1100 CO Monitor is factory calibrated to detect lethal carbon monoxide gas using Advanced Gas Sensor (AGS) Technology™. This technology uses sophisticated software with a solid state sensor that requires no routine bump testing or calibration. The AI-1100 is a great value for those situations where only an audible or visual alarm is needed for detecting carbon monoxide gas.
The Airspace AI-1200 CO Monitor contains all the features and performance of the AI-1100 model while adding a front panel LCD display that shows gas levels in parts per million (ppm). The new Airspace “Rev 2” design includes a white backlight for reading ppm levels in low light conditions and a red flashing light through the LCD screen. This is in addition to the high intensity LED light and results in dramatically improved visible alarm performance.
