The meaning of use of residual chlorine detector and total chlorine detector

With the extensive use of chlorine-containing disinfectants, words such as residual chlorine frequently appear in the public eye during use. I mainly introduce the detection significance of residual chlorine detectors and total chlorine detectors, residual chlorine detectors and total chlorine detection. The instrument adopts the DPD national standard method, imitates the design of ergonomic principles, is small and light, and uses chemometric statistics to intelligently analyze multiple sets of data to make the test results more effective and reduce the measurement error. The 8-inch color touch screen guides the operation, and the humanized interface design makes the operation easier and easier to understand. Imported LED cold light, optical performance and corresponding prefabricated reagents are equipped as standard, which greatly reduces human error and detects quickly. The residual chlorine detector and the total chlorine detector can be widely used in the detection of medical sewage, industrial sewage, drinking water, swimming pool water, cooling circulating water and other fields.
