Model GID-3 recently received an ACADA (Automatic Chemical Agent Detector Alarm) contract from the U.S. Department of Defense to help protect troops in combat zones. The detector can be carried by soldiers, mounted on vehicles or in bunkers, installed around fixed sites for perimeter defense, or integrated into filtration systems and alarm networks. Continuously monitors areas to indicate presence of nerve and blister chemical agents, along with the level of danger. Can also be programmed to sense additional threats, such as blood and choking agents. Response time is about 3 secs. Emits audible alarm, as well as visual alarms to local and remote locations. Works through Ion Mobility Spectrometry (IMS) technology. Resists shock, vibration, harsh wea-ther, dust, and sand. Runs on battery or a.c. power supply. Data port provides information in RS232 format.
