1201 Carbon Monoxide and Methane Monitor
Methane alarms at 5000 ppm.
Visual and Audio alarms at CO level of 30 ppm, 60 ppm, and 120 ppm

Has all the features of the AI-1200 model and adds LEL capability that is calibrated to methane. The calibration to methane was chosen because it can be a "silent" gas you can't see or smell in its pure form. You can count on the Airspace monitor to give you an accurate reading for methane gases you might otherwise not know are there. Like all LEL sensors, it will also "see" most hydrocarbon gases – such as gasoline, propane, natural gas, hydrogen, acetylene, etc. It won't give an accurate ppm reading for those other gases because the calibration is to methane, but it will be very useful since any ppm reading for those other gases will be an indication an ambient air saturation – therefore an explosive hazard – is occurring. No ppm reading is an indication the gases are dissipating and an explosion is therefore less likely.

*Our SnifTM technology updates every 4 seconds when in alarm. This feature will allow searching for the source of CO or monitoring trends, i.e.; does opening a window help.
