Brief introduction
YJD-201C portable water quality alkalinity hardness testerUsing a monochromatic cold light source, the data is automatically processed by a microcomputer to directly display the alkalinity concentration value of the water sample. Adopting a handheld design is the best choice for outdoor use; The instrument adopts imported light source, with fast, accurate and stable measurement, simple and safe operation. Widely applicable for the determination of surface water, groundwater, sewage, and industrial wastewater.
