CO2 Control In School Classrooms - AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

Scientists Build Hand-Held CO2 Tester for the Classrooms

If CO2 levels rise too high they say, school officials can call impromptu recess to get the kids outside breathing healthier air, while giving the classroom time to rejuvenate its oxygen supply. The new device is called a dual beam sensor because it emits two beams of light that it uses to sense the levels of CO2 around it. It’s considered twice as accurate as previous sensors and can be ...
