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 ...
