zNose deployed in Chinese petrochemical disaster

The zNose detection system from Newbury Park, California-based Electronic Sensor Technology (OTCBB: ESNR) is being deployed by China’s Heilongjiang Environmental Protection Agency (HEPA) to test the contaminated water in northeastern China caused by a recent chemical plant explosion.
