NEWBURY PARK, Calif.–Electronic Sensor Technology (EST) (OTCBB:ESNR), a leading provider of innovative homeland security and environmental solutions, today announced that it has introduced the Air Guardian with enhanced performance and detection capabilities. The Air Guardian is now able to detect nerve agents in addition to explosives and toxic chemicals. These enhancements will enable EST to better participate in TSA’s new “Community Policing Program” designed to add security to the nation’s airports.

The Air Guardian system can be operated over a LAN network 24/7 to provide unattended detection capabilities, and issue custom responses to detected threats. Several Air Guardian instruments can be operated from one control console which may be interfaced with the communication network.

The Air Guardian will provide a needed layer of security for the detection of nerve agents, explosives, and toxic chemicals in entry areas, secure spaces, and other sensitive locations within airports or buildings.
