Tips: What is TDS/PH?

TDS (Total Dissolved Solids) and pH (Potential of Hydrogen) are two important parameters used to assess the quality of water or any liquid. TDS represents the total concentration of dissolved substances in water, typically including inorganic salts like calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates, as well as some organic matter. TDS is usually measured in parts per million (ppm), indicating how many milligrams of dissolved substances are present in one liter of water. TDS levels help determine the purity of water, with low TDS indicating higher purity and high TDS suggesting possible contamination or a high mineral content.

pH measures the acidity or alkalinity of a solution, ranging from 0 to 14 on the pH scale. A pH of 7 indicates a neutral solution, values below 7 indicate acidity, and values above 7 represent alkalinity. pH is measured using a pH meter or strips, and the scale is logarithmic, meaning small changes in pH correspond to significant shifts in acidity or alkalinity. pH levels are important for chemical reactions in water, influencing biological processes, corrosion, and water treatment. For example, drinking water typically has a pH level between 6.5 and 8.5.
