Product Details
DGB-403F portable residual chlorine dioxide chlorine analyzer is designed and developed based on DPD colorimetric method. It can directly measure residual chlorine, total chlorine and chlorine dioxide in water. It is convenient, accurate and reliable. The method is in line with the national standards for determining relevant indicators in the field of water quality analysis, and is widely used for the determination of residual chlorine, total chlorine and chlorine dioxide in drinking water, landscape water, medical wastewater, swimming pool water, disinfectant and the like.
