OEM-3, Ozone Detection and Control Board for OEMs
Please ask for a quotation for your OEM quantities!
The model OEM-3 is designed to control ozone generators and alarms based on an adjustable ozone concentration set point.
The sensors modules can also be located at a distance from the OEM-3 boards by optional 2m or 8m (6ft or 25ft) cables. These are readily available wire extension cables.
The OEM-3 should not be used outdoors or in the presence of NOx, nitric acid, acid gases, or halogen compound fumes.
