Electronic Sensor Technology

Electronic Sensor Technology, Inc. is engaged in the development, manufacture, and sale of zNose, a device designed to detect and analyze chemical odors and vapors. The zNose identifies the chemical makeup of any fragrance, vapor or odor. The zNose does this by creating a visual image of the fragrance, vapor or odor that it detects, so that the user of the zNose may identify the fragrance, vapor or odor. VaporPrint allows the user of the zNose to see a visual image of the makeup of a particular fragrance, vapour or odor within 10 seconds. VaporPrint images are displayed on a laptop computer screen and are recorded on the hard drive of the laptop computer. During December 31, 2008, the Company developed four zNose models designated as Model 4200 (Handheld Unit), Model 4300 (Portable Unit), Model 7100 (Bench Top Unit), and Model 8100 (Fixed Installation Unit).
