Conductivity of electrolytic water machine

Conductivity refers to the property of common substances in tap water that can conduct electrons. In aqueous solutions, similar terms are "electrolytes", commonly known as ionic compounds, which can be measured by TDSmeter.
For example, water with a hardness of about 150mg/L has a TDS value of about 280ppm, and the main components are "calcium sulfate" and "calcium bicarbonate", as detailed in "hard water".
