Electronic Sensor Technology has received an order from Northrop Grumman Corporation, a leading defense contractor and shipbuilder distributor, for three zNose devices. The devices are expected to be used for cargo detection in Louisiana as part of Northrop Grumman's security integration project for the U.S. Navy. The zNose is an electronic sensor device that can capture and analyze nearly any odor, fragrance or chemical vapor within ten seconds, for security and defense applications.
