Portable Suspended Solid Meter MLSS-1708 The portable suspended solid meter(portable mlss meter) consists of a host and a suspension sensor. The sensor is based on a combined infrared absorption scatter ray method, and the ISO 7027 method can be used to continuously and accurately determine the suspended matter (sludge concentration). The suspended matter (sludge concentration) value was determined according to ISO 7027 infrared double scattering light technology without chromatic influence. Application:Widely used in on-site portable monitoring of water suspended solids in sewage treatment, surface water, universities, research institutes, etc.
