The zNose, a product of Electronic Sensor Technology Inc., is an electronic nose with part per trillion sensitivity, which can detect and analyze a sample in less than 10 seconds. The combination of the zNose and its Remote Sampler enables first responders the ability to detect and quantify suspicious odors in remote, inaccessible locations. The Remote Sampler, a self-contained unit, weighs approximately 12 ounces and enhances the sensitivity of the zNose by more than 100 to 1. This eliminates the need to carry heavy and bulky equipment for long periods of time.
