GA-DCS025 can be used to test 25 parameters. Easy and fast to operate, just added reagents after zero calibration , and then to complete the measurement by reading. It can be widely used in city water supply, sewage treatment factory,pure water,beverage factory, food factory, environmental protection departments, industrial water, and epidemic prevention departments, urban water supply,the environment, health care, chemical, pharmaceutical, aquaculture, biotechnology, fermentation process, textile, petrochemical, water treatment and other areas for fast test and laboratory standard test of water quality. 

GA-DCS025is a single fixed wavelength spectrophotometer, which adopt the principle of spectrophotometry to measure the parameters. In the instrument, the linear curves of the concentration of different parameters and the absorbance were established, and the concentration of the water samples was obtained through the identification of the color.
