RS485 interface Low Turbidity Probe For Sewage Discharge Detection
The turbidity sensor is a continuous monitoring instrument probe that is widely used in environmental protection, pharmaceutical, biochemical, food and tap water solutions for continuous monitoring of turbidity and temperature.
The product probe uses the principle of laser scattering to measure the turbidity of water quality. The laser scattering method has been active in recent years, which can overcome the shortcomings of traditional classical measurement methods that cannot be continuously measured online.
The laser scattering method is stable in measurement, free from magnetic field interference, and does not consume probes. Sensitivity High, low detection limit, long life, continuous online monitoring and other advantages have been widely used.
