Total phosphorus is the sum of water particles and dissolved organic phosphorus and inorganic phosphorus, Total phosphorus reflect the extent of water contamination by phosphorus. An increase in the content of phosphorus in water can cause eutrophication, resulting in blooms or red tide occurred, seriously affecting water quality. 

Features: 
Instruments complete digestion than one color, simple and reliable structure, reducing potential errors. 
Imported modified PTFE transparent hose, diameter greater than 1.5mm, reducing the chances of blockage of water-like particles. 
Can automatically clean sampling pipes to prevent algae or biofilm formation. 
Error reset and power off the call, the instrument automatically discharge the residual reactants instrument automatically return to work status. 
Low failure rate, maintenance, less reagent consumption. 
Intelligent self-diagnostics, alarm, equipment management and maintenance very convenient. 
Imported PLC control devices to reduce environmental interference and equipment failure. 
Multi-channel valve, strong corrosion resistance, long life, safe and reliable.

Applications: 
Total phosphorus adapted in 0 ~ 50mg / L range wastewater. Most common ions do not interfere with the determination, but for some samples contain large amounts of organic matter, the measurement results may be low.
