  • CO Monitor

    AI-1200 - Airspace Monitoring Systems

    AGS with Snif technology, and now with a backlit LCD display, the 1200 monitor will accurately measure and display CO levels from 12 ppm to 250 ppm. It also includes alarms like the 1100 with a panel of flashing lights and 92 decibel audio that begins at 30 ppm and grows in intensity to 120 ppm. The Snif technology provides an update every 4 seconds when in alarm to help you find the source, see the trend and otherwise manage the CO event. Like all of our V2 models, it now has a motion switch option built into it. When motion switch management is chosen, the monitor will turn itself on by any movement and if it doesn't sense CO or hasn't moved in 45 minutes, it will shut itself off. The motion switch allows passive screening capability that can dramatically stretch your battery life without risk of forgetting to turn the monitor on or off. Like all of our monitors, there is no routine bump testing or calibration required and the monitor is warranted for five years, even the sensor and its calibration is included in the warranty.
