NADE SD9025 Water Quality Tester/Analyzer test for drinking water quality(Cl2,ClO2,NHCl2,NO2-N)

photoelectric colorimetric detection principle to replace the traditional visual colorimetric method. Eliminates human error and has high measurement resolution. When the test ion in the water reacts with the DPD reagent during the measurement, the water sample will turn pink. Then put the water sample into the photoelectric colorimetric base of the instrument, and the instrument will obtain the corresponding ion concentration value by comparing the color depth. It can be widely used in water plants, industrial and mining enterprises, hospitals, domestic or industrial water inspection departments, etc., in order to control the ion concentration in the water to meet the prescribed water quality standards. This instrument complies with the national standard <GBT 5750.11-2006 Standard Test Method for Drinking Water> as the method for measuring disinfectant indicators.

l Using large-scale integrated circuits to ensure that the instrument can work stably for a long time. The memory standard curve can be modified by the user, and it has the function of power-off save;

l Reliable positioning structure and independent light path system can effectively avoid the interference caused by stray light, and can accurately determine the ion concentration value in the sample;

l The selection of light source, detector and working curve can be completed automatically. It has a high degree of automation and simple operation;

l Equipped with high-intensity and long-life cold light source, no worries about replacement. Optional built-in

l printer;

l Self-developed rapid determination reagents that meet national standards can be supplied stably for a long time, effectively reducing user workload and sample testing costs.
