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-1201 CO/Methane Monitor extends the capabilities of the AI-1200 model to include detection of methane and other flammable or explosive gases. Carbon monoxide and methane levels will display in parts per million (ppm). Natural gas, propane, gasoline, hydrogen, acetylene, benzene and toluene are just some of the other gases that will be sensed by the AI-1201 Monitor. The monitor is set to alarm for methane at 5000 ppm and alert for potentially explosive situations. The carbon monoxide monitors have three alarm levels – low, medium, and high.
