OPERATING PRINCIPLE
Organic compounds containing conjugated double bonds or poly- cyclic aromatic hydrocarbons absorb ultraviolet(UV)light when dissolved in water.By measuring the absorbance of UVlight at 254 nm,the degree of organic pollution in the water can be assessed. The "Specific UV Absorbance,"SAC254,is a physical parameter used to quantify the total organic content.An infrared light path is used as a reference to compensate for turbidity interference.
PRODUCT APPLICATION
· Online COD/BOD monitoring at the inlet,biological tanks, high-efficiency sedimentation tanks,and denitrification filters in wastewater treatment plants
· COD/BODmonitoring in rivers,lakes,seawater,and aquaculture environments
PRODUCT FEATURES
· UVabsorbance measurement technology with high accuracy
· Dual optical path design minimizes interference from color and turbidity
· Reagent-free operation,no secondary pollution,and reduced operational cost
· Long-lifespan,energy-efficient light source with stable intensity
· Specialized structural design prevents bubble and impurity accu- mulation,ensuring stable measurements
· Equipped with brush-type self-cleaning system for mainte- nance-free operation and reduced O&M cost
