Product details
DYZ-A2 wall mounted, circulating multifunctional low turbidity detection online turbidity meter
Main Performance Overview:
Turbidity meter uses 90 ° scattered light for online measurement of medium and low turbidity;
The instrument consists of a voltage stabilizing defoaming device, sensors, and a display;
The turbidity sensor adopts an infrared laser scattering mode detector;
LCD backlight display on the monitor, keyboard operation for various settings;
The first domestically developed sensor with high sensitivity in the low turbidity range
Stable and reliable, fast response speed, accurate data;
The instrument itself stores the last 1000 sets of data for browsing and querying;
Install random software, connect to the computer, measure data storage, view and analyze, print and other functions;
The technical indicators of the turbidity meter have reached the level of similar international products.
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 brick based bubble elimination system
● Cleaning and maintenance are very simple; Calibrate once every three months
● Good reproducibility, unaffected 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； There are multiple auxiliary measurement units 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 bubble removal system that can remove air bubbles carried in the sample stream, thereby eliminating significant interference in low turbidity measurements; The defoaming system is not affected by changes in sample flow rate and pressure.
