Zinc pollution is the environmental pollution caused by zinc and compounds. The main sources of pollution have zinc mining, smelting emissions processing, machinery manufacturing and galvanizing, instrumentation, organic synthesis and paper industries. Tire wear and dust produced by coal combustion, soot containing both zinc and compounds, Industrial waste water often zinc in zinc hydroxy complexes exist. 
Features: 
Cuvette unique design, with higher sensitivity and numerical stability; 
Intelligent self-diagnostics, equipment management and maintenance very convenient; 
Error reset and power off the call, the instrument automatically discharge the residual reagents automatically return to work status; 
Network-capable, through the network, remote control data can be realized; 
It has anti-control functions via remote control in the increased ease of operation; 
Imported PLC control devices to reduce environmental interference and equipment failure; 
Using sequential injection analysis, flow path is simple, low reagent consumption, high degree of automation; 
Multi-channel valve, strong corrosion resistance, long life, safe and reliable.
