In March 2015, the "Notice of the Ministry of Water Resources on Further Strengthening the Purification, Disinfection, and Testing of Water Quality in Rural Drinking Water Projects" (Shui Nong [2015] No. 116) required that water plants with more than 10 million people must establish water quality laboratories. Water supply units should establish a water quality inspection system, equip inspection personnel and equipment, and carry out regular testing of source water, factory water, and terminal water according to the scale and specific situation of water supply. Having the ability to perform nine routine daily tests, including chromaticity, turbidity, odor and taste, and visible substances to the naked eye PH、 High manganese salt index (CODMn), total bacterial count, total coliform bacteria, and disinfectant residue.
Our company has specially equipped a daily portable water quality comprehensive testing box for rural drinking water projects, which is used for daily water quality testing in water plants and can also meet the inspection work of source water and pipe network end water.
1 Portable, fast, and easy to operate
Handheld unique design, easy to carry with you. The operation interface is simple and easy to understand, with low requirements for operators. Finished pharmaceuticals are convenient, fast, stable, and reliable.
2 Reasonable cost and convenient use
The detection principle conforms to the national standard method, and the detection results are traceable. The testing items include nine items for factory water, and can be extended to other testing items such as fluoride, iron, manganese, etc. without adding other hardware.
3 Accurate detection and complete items
The detection box contains multiple items, has low reagent consumption costs, reasonable post use costs, and can effectively operate for a long time.
4 Widely applicable for testing in rural water plants
Solved the problems of complex water quality testing operations, high costs, and unstable testing results in rural water plants.
