SAW MiniCAD mk II™ Miniature Chemical Agent Detector
The SAW MiniCAD mk II Detector uses a pair of Surface Acoustic Wave (SAW) microsensors. SAW sensors are piezoelectric crystals that detect the mass of chemical vapors absorbed into chemically selective coatings on the sensor surface. This absorption causes a change in the resonant frequency of the sensor. The internal microcomputer measures these changes and uses them to determine the presence and concentration of chemical agents. The SAW sensor coatings have unique physical properties which allow reversible adsorption of chemical vapors.
