PITTSBURGH, Pa. – MSA says its Surface Acoustic Wave (SAW)  MiniCAD mk  personal chemical agent detector uses proven surface acoustic wave sensing technology to simultaneously detect trace levels of nerve and blister agents.

Highly selective to these agents and extremely resistant to false alarms, the lightweight solid-state detector sets a new standard for instrument ease of use and reliability, according to the maker.

MSA says first responders in a wide variety of organizations have made the MiniCAD detector their first choice in detection of chemical warfare agents.

It operates from either standard off-the-shelf lithium batteries or a rechargeable battery pack and uses proven SAW sensor technology. It weighs 18 ounces including batteries.

It has set the standard for instrument ease of use and reliability, according to MSA, as First Responders in a wide variety of organizations have made MSA’s MiniCAD Detector their first choice in detection of chemical warfare agents.

MSA’s SAW MiniCAD has fully automated operation, is compact and portable, has LED and audible alarms, and uses solid-state surface acoustic wave microsensors.

The detector also has a quick warm-up time, a 60-second cycle time, records data, requires no user maintenance and has a 5-year shelf-life.

A battery charger, a soft protective case, four lithium batteries and a hard, waterproof carrying case are included.

SAW MiniCAD’s microsensors are piezoelectric crystals that detect the mass of chemical vapors absorbed into chemically selective coatings on the sensor surface, according to MSA. 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.
