Electronic Sensor Technology Inc (ESNR)

[Z-NOSE]

The zNose has any number of functions and uses. EST hardly ever puts enough information in it's PR's. Nor do they do follow up PR's on the companys using the products. It always seems to be a secret, with a publically trading company? I realize that some sales require an NDA agreement, but it cannot be all sales. This company is doing a lot better than we know IMHO. If they only knew how to promote themselves.
Good luck.
