Description

Technical Field

[0001] The utility model relates to the technical field of pure water detection, in particular to pure water equipment with a TDS detection sensor. Background Art

[0002] TDS (Total Dissolved Solids) water quality tester is an instrument used to measure the concentration of total dissolved solids in water. Total dissolved solids include dissolved salts, minerals, inorganic ions and other soluble substances in water, which have a good correspondence with the hardness and conductivity of water. The smaller the TDS value, the lower the concentration of plasma in the water and the smaller the conductivity. The TDS value is generally used to measure the purity of pure water, but a small TDS value does not mean good water quality, and a high TDS value does not mean poor water quality. Qualified drinking water standards must meet microbial indicators (bacterial count), toxicological indicators (concentration of heavy metal plasma), sensory properties (color, smell, taste, visible to the naked eye), general chemical indicators and radioactive indicators. Healthy and clean domestic water must not contain pathogenic microorganisms, and chemical substances and radioactive substances in the water must not endanger human health. The sensory properties must be good. In drinking water, excessive concentration of heavy metal ions will pose a great threat to human health. For example, the allowable safe concentration of lead, arsenic, chromium, cadmium, and mercury is 1-10 mg / L. The size of the TDS value can reflect the concentration of harmful heavy metal ions in most water. The number of bacteria in the water, the concentration of organic matter, whether the nitrite concentration exceeds the standard, and whether there are pesticide residues cannot be reflected by the size of the TDS value.

[0003] At present, a TDS detection device is needed to detect pure water, but the pure water equipment and TDS detection are separate, which makes it troublesome to detect pure water and cannot be detected in time. For this reason, we designed a pure water equipment with a TDS detection sensor to increase the ability of pure water equipment to detect water quality. Utility Model Content
