TSS (Sludge concentration) in sludge: 0 - 10% solids

Measurement

Small transducer for easy inline installation.

Superior resistance to

fouling & struvite precipitation
changes in optical parameters (e.g. changing colour)

Easy mounting due to the compact sensor.

Hot-tap retractable possible (other version - See OTD-SDXA)

Standard maintenance interval longer compared to optical sensors

Factory calibrated
