Typical applications:
Water treatment plant: turbidity monitoring of pre filtration, post filtration, sedimentation, and effluent water; Monitoring of water quality in municipal pipeline networks;
Industrial process water quality monitoring, circulating cooling water, activated carbon filter effluent, membrane filtration effluent, etc

Instrument features:
● Built in patented bubble elimination system
Cleaning and maintenance are very simple; Calibrate once every three months
Good reproducibility, not affected by sample flow rate and pressure
● Adopting the two-point correction method of 0 and 20NTU - recommended correction method
● Single point calibration can also be done through comparison: (choose any point within the range of 1-40NTU)
● Measurement unit: NTU; Multiple auxiliary measurement units are displayed simultaneously: FTU, TE/F, mg/L
● Methods recognized by USEPA (United States Environmental Protection Agency)

Measurement principle:
The incandescent light emitted from the sensor light source component enters the turbidity meter downwards and produces scattered light when encountering suspended particles in the sample. The photodetector immersed in the water sample can detect scattered light at a 90 ° angle to the incident beam.
The continuously flowing water sample flows through a patented bubble removal system, which can remove air bubbles carried in the sample stream, thereby eliminating the most significant interference in low turbidity measurements; The defoaming system is not affected by changes in sample flow rate and pressure.
