Drinkingwater/surface water/industrial production process water/wastewater treatmentand other fields, continuous monitoring of dissolved in the water, theconcentration of nitrate, especially suitable for monitoring sewage aerationtank, control the denitrification process.
Absorptionof 210nm in water by NO3-. Therefore, we can measure theconcentration of NO3-N in water by measuring the absorption ofultraviolet light to 210nm. When the sensor is working, the light emitted bythe light source passes through the sample and reaches the detector on theother side of the sensor.
● A highly accurate method of ultraviolet absorption;
● No sample pretreatment, fast reaction analysis;
● Do not need any reagent, no two pollutions;
● Sensor with self-cleaning function, basic maintenance free;
● Save reagents and maintenance costs, low operating costs.
