The working principle and main features of the three-in-one online water quality analyzer

The triple of the three-in-one online water quality analyzer refers to the three parameters of COD, ammonia nitrogen, and total phosphorus. The instrument is a simultaneous determination of COD, ammonia nitrogen, and total phosphorus. Working principle: After the water samples pass through the pretreatment device, they are sent to the respective reaction pools, and then the UV spectrometry of COD is carried out. At the same time, the chemical reagents used for the measurement of ammonia nitrogen and the digestion solution used for the measurement of total phosphorus are added to the two reaction pools respectively. Solution and chromogen for the color reaction of ammonia nitrogen and total phosphorus. The content of COD, ammonia nitrogen and total phosphorus in the water sample can be calculated by measuring the absorbance value of each reaction cell solution. Main features: 1. It is a three-in-one water quality online analyzer that integrates online COD, ammonia nitrogen and total phosphorus in China. One instrument can measure three parameters of COD, ammonia nitrogen and total phosphorus at the same time, which reduces the user's use cost by 70% %; 2. The water sample pretreatment device adopts a maintenance-free design, which can ensure that the maintenance period of the pretreatment device exceeds half a year; 3. The chemical reaction time can be adjusted, and the measurement process and results meet the relevant standards; 4. COD ammonia nitrogen and total phosphorus three-in-one The online analyzer can adjust the quantitative sampling device to ensure that the instrument can accurately measure various water samples by adjusting the amount of reagents and sampling volume; 6. All imported devices and innovative analytical flow path design and reagent formula ensure high measurement reproducibility, and the current measurement reproducibility can reach 5%; 7. Fully automatic operation, no need for personnel on duty , can realize automatic zero adjustment, automatic standard, automatic measurement, automatic cleaning and other intelligent functions; online monitoring methods are diversified, and can realize manual measurement at any time, automatic timing measurement, automatic periodic measurement and other measurement methods.
