Based on 90-degree optical scattering, these sensors measure the concentration of tiny suspended particles in water in real time. Precision optical windows include automatic cleaning functions to prevent measurement deviations caused by biofouling. They are widely used in filter efficiency monitoring at waterworks and surface-water environmental monitoring, serving as key tools for quantifying water clarity.
The SensorsX SX-CTNCA Series is a self-cleaning turbidity sensor designed for continuous water quality monitoring. It uses the 90° scattering method compliant with ISO 7027, supports measurement ranges up to 4,000 NTU, and features RS-485/Modbus communication, IP68 protection, and an integrated cleaning brush for stable, low-maintenance operation in industrial and environmental applications.
