ABSTRACT:
An air-borne chemical sensor system includes a motor and impeller to draw an air sample into a housing containing a sensor which will provide a signal for display related to the amount of a particular air-borne chemical in a given air sample. The system is controllable by different duration activation of a single activating switch which can further control a secondary function, such as a flashlight.
