The Model 3001 Biofoul Screen is an affordable option to lengthen the time a Levelogger 5, Levelogger 5 Junior, Levelogger 5 LTC, LevelVent 5, or AquaVent 5 can be deployed before maintenance is required. Using the natural anti-fouling characteristics of copper, the Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels. The Biofoul Screen consists of a Delrin® sleeve wrapped with copper wire. The Biofoul Screen simply slips onto the sensor end of the datalogger, where it is held in place by compression f it. The screen allows water to freely enter the pressure sensor of any Solinst datalogger, and the conductivity cell of an LTC.
