Permanganate index is reflected in water of organic and inorganic oxidizable substances commonly used indicators. Is defined as: under certain conditions, with certain organic permanganate oxidation of water and inorganic reducing substances, calculated from the amount of potassium permanganate consumed a considerable amount of oxygen. 
Features: 
The instrument uses GB11892-89 "Quality -Permanganate index measuring the" standard; 
Power protection design, with power, then power automatic data recovery; 
Intelligent self-diagnostics, equipment management and maintenance very convenient; 
Patented design, product failure rate, low maintenance, low reagent consumption; 
Suitable for surface water sources and measurements can be applied to sewage Water treatment process testing; 
Network-capable, through the network, remote control data can be realized; 
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.

Applications: 
Chemicals: pharmaceutical, chlor-alkali chemicals, dyes pigments, pulp and paper, intermediates, fertilizers, starch, cornstarch, pesticides, metallurgy, adhesives, detergents and other industries; 
Water treatment: air scrubbers, boiler feed water, cooling water, water power plant; 
Wastewater: electroplating wastewater, Industrial waste water, heavy metal precipitation.
