1、 Introduction to Drinking Water Quality Testing Instruments
TC-BMLSThe portable drinking water quality detector is a multi parameter water quality detector developed and designed by our company in accordance with national standards and industry needs. The multi parameter water quality detector is equipped with multiple wavelength light sources, and the wavelength is automatically selected. It can detect conventional indicators (pH, conductivity, etc.), heavy metal indicators (mercury, chromium, manganese, copper, etc.), inorganic salt indicators (residual chlorine, total chlorine, phosphate, etc.), and microbial indicators in drinking water. In addition, this multi parameter water quality detector is equipped with a micro thermal printer that can directly print experimental data; Widely used in various industries such as laboratories, sewage treatment plants, universities, environmental monitoring departments, research institutions, etc. for the testing of drinking water.
