photoelectric colorimetric water quality analyzer

DGB-424

Product info

Product Details
DGB-424 photoelectric colorimetric water quality analyzer adopts new LED testing technology, integrates LED light source with specific absorption peak wavelength, built-in standard curve, directly uses colorimetric tube as measuring container, compact size, convenient for user operation and carrying. This series of products can measure the residual chlorine and total chlorine parameters (this series of instruments can expand the custom ammonia nitrogen, total phosphorus, permanganate index, aluminum, total hardness, residual chlorine, total chlorine, chlorine dioxide, urea and other project parameters. ), applicable to on-site measurement or laboratory analysis of surface water, industrial wastewater, medical wastewater, landscape water for drinking water, drinking water, swimming pool water, etc.
