Introduction: MLSS-99 online sludge concentration meter application areas: 1. Sewage treatment plant-water inlet, outlet, aeration tank, return sludge, primary sedimentation tank, secondary sedimentation tank, thickening tank, sludge dewatering, etc. 2. Water plant -Filter backwash water, raw water and sedimentation tank effluent. 3. Others—Industrial production process/circulating cooling water and other water quality testing. Features: 1. Using optical band-pass filtering and modulated excitation light, effectively avoiding the influence of ambient light and water color on the measurement data; 2. Built-in light source compensation measurement circuit, which can effectively compensate the intensity attenuation of the light source; 3. The sensor comes with a wiper cleaning function, which effectively prevents the light window from staining; 4. Scratch-resistant toughened glass is used to effectively reduce light path changes caused by scratches on the light window; 5. Automatic conversion of measurement methods to adapt to a large range; 6. The sensor is equipped with self-diagnosis function to ensure the accuracy of the data; 7.240*160 graphic dot matrix liquid crystal, with LED backlight, can be operated under direct sunlight; 8.
