Dissolved Oxygen Probe Membrane Cleaning System From Sensorex

The WPR12 membrane cleaning system provides continuous, automatic wiping of the sensor to prevent membrane fouling.  A solenoid actuated assembly sweeps a nylon brush across the membrane surface, preventing biofilm build-up that causes sensor fouling.   Also the agitation moves the sample water across the sensor membrane, allowing for more accurate measurement.  This movement prevents measurement problems often associated with installations in stagnant water.

Mounting hardware is provided with each WPR12 wiper system.  The hardware allows for adjustment of brush tension against the membrane.  Use more tension for heavy fouling applications or adjust the sensor so that the brush is near the membrane and provides a gentle sweeping action with just enough flow to meet minimum flow requirements.
