ABSTRACT:
A programmable atmospheric stabilizer uses one or more sensors for detecting the condition of potentially hazardous materials within a container or some other enclosed atmosphere. The sensors connect to a first threshold detector which activates a first order correcting device when the sensor detects a first order hazard. The sensor also connects to a second threshold detector which activates a second correcting device when the sensor detects a second order hazard. The first correcting device may be a fan, and the second correcting device may include an alarm. A variety of different sensors can be connected to one monitoring unit and a variety of different correcting devices can be activated by the monitoring unit. Each monitor can be connected to a central location where the sensed levels and the activity of the correcting devices can be monitored. The threshold levels at which each of the correcting devices are activated can be adjusted independently and when the monitors are coupled to a central control unit the correcting devices can be controlled from the central location. The monitor acts independently and is suitable for different applications including hazardous storage containers, manufacturing plants, parking structures, and office buildings.
