Toxic chromium valence related to its presence, usually considered toxic Hexavalent chromium is 100 times higher than the price of three, Hexavalent chromium is more easily absorbed by the body and accumulate in the body, causing liver cancer. Therefore, our 已把 Hexavalent chromium predetermined one of the indicators for the implementation of total control. 

Features: 
Using GB / T7467-87 "Determination of Water Quality -Hexavalent chromium diphenyl hydrazine spectrophotometry"; GB / T7466-87 "Determination of Water Quality -Total chromium"; 
Intelligent self-diagnostics, equipment management and maintenance very convenient; 
With automatic range switching function without manual setting; 
Have anti-control function, the instrument can be controlled by remote control in the increase ease of operation; 
You can set time intervals, telemetry and other sampling methods; 
Error reset after a power failure and calls the instrument discharge residual reactants and automatically return to work status; 
Ideal for surface water, groundwater, sewage and other detection process; 
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.
