In Pipe Low Range TSS Sensor 

The Australian designed and built S73P In Pipe Low Range TSS Sensor has the same technical specifications as our S73D MLSS Sensor used in Waste Water Treatment Plant Aeration Basins. 

The RWT S73P Sensor can be mounted directly into a pipe via a taping band or weld in socket arrangement. 

It also has an in-built nozzle for automatic air or water thus minimising the requirement for mechanical cleaning by maintenance staff. The RWT S73P comes with a base calibration from the factory. However, it can be calibrated to your laboratory sample test when combined with a MXD73/75. 

Applications include return sludge lines and pits, SBR systems, primary clarifier effluent and wastewater monitoring for industrial plants.
