Online Turbidity/Suspended Solids (Sludge Concentration) Sensor

Immersible Online Turbidity/Suspended Solids (Sludge Concentration) Sensor

MODEL NO： TS-2000

APPLICATIONS：

Sewage treatment plants: Inlet and outlet water, aeration tank, return sludge, primary settling tank, secondary settling tank, concentration tank, sludge dewatering, etc.
Others: Industrial production processes, circulating cooling water, and other water quality monitoring.

Product Features

Measures both turbidity and suspended solids (sludge) concentration.
Dual-beam infrared scattering detection technology.
Utilizes optically bandpass filtering and modulated excitation light to effectively eliminate the influence of ambient light and water color on measurement data.
Built-in light source compensation measurement circuit effectively compensates for the intensity attenuation of the light source.
Sensor with built-in wiper cleaning function to prevent contamination of the optical window.
Uses scratch-resistant toughened glass to minimize optical path variations caused by window scratches.
Automatic range conversion to adapt to a wide range of measurement ranges.
