Mixed Liquor Suspended Solids Measurement (MLSS)

SSP 200 Mixed Liquor Suspended Solids

Precision mixed liquor suspended solids probe with compensation of soiling.


  • Minimum maintenance
  • Short response time
  • Long lifetime
  • Wide measuring range
  • Robust design
  • Easy to install

SSP 200 applies a dual beam method with two optical paths of different lengths. Transmission on these two optical paths decreases with increasing number of particles. The MLSS content (dry mass) of the sample is then determined from these two transmission values.
