GE-139 Turbidity Monitor Meter

GE-139 Turbidity Monitor Meter is one industry grade online analytical instruments, it offer a suitable solution for the monitoring of final effluent water discharge to ensure compliance with Environmental Agency regulations. The Turbidity Measurement Meter is suitable for the monitor of turbidity concentration in Water Treatment Plant, Reservoir, Sewage Treatment Plant, water quality testing and management, river monitoring, stream measurement, reservoir water quality testing, groundwater testing, water and wastewater treatment, and effluent and industrial control. 

According the Light scattering theory, the scattering of light was thought of as the redirection of light that takes place when an electromagnetic wave (i.e. an incident light ray) encounters an obstacle or non-homogeneity, the turbidity concentration is directly proportional to the scattering of light, when the light go through the liquid, as this theory. The turbidity sensor directs a focused beam into the monitored water, The light beam reflects off particles in the water, and the resultant light intensity is measured by the turbidity sensor's photodetector. The light intensity detected by the turbidity sensor is directly proportional to the turbidity of the water.
