An airborne hazardous material reader device capable of receiving a collection element. The reader device has a body forming a slot area for receiving the collection element. The body has a crushing mechanism located within the slot area for breaking ampules attached to the collection element containing chemical testing reagents, a micro-pump positioned proximate to the slot area for controlling the temperature next to the collection element, a diode reading component incorporated within the body for distinguishing color changes from the release of chemical testing reagents from the broken ampules, an indicator for indicating the presence of a hazardous material when the diode reading component distinguishes color changes and a microprocessor that coordinates the sequence of the reader device. A method for airborne hazardous material detection also is disclosed.
