Nickel is a silvery white metal with magnetic, stable at room temperature in air, which is not active element. Nickel is easy with nitric acid, hydrochloric acid or sulfuric acid and dilute the role of slow. Nickel exists in nature in various minerals, often combined with sulfur, arsenic or antimony. In mining, smelting, alloy production, metal processing, electroplating, chemical, ceramics and glass and other industrial waste water may contain nickel. 
Features: 
Stable, easy operation and maintenance, low operating costs; 
Intelligent self-diagnostics, equipment management and maintenance very convenient; 
With automatic range switching function without manual setting; 
It has anti-control functions via remote control in the increased ease of operation; 
You can set time intervals, telemetry and other sampling methods; 
Error reset, power off the call, the instrument discharge residual reactants and return to work status; 
Ideal for surface water, groundwater, sewage Water treatment processes such as detection; 
Network-capable, through the network, remote control data can be realized; 
Imported PLC control devices to reduce environmental interference and equipment failure; 
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.
