What is TDS?
Total Dissolved Solids (TDS) refers to any minerals, salts, metals, cations or anions dissolved in water. Total dissolved solids comprise of inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates) and some small amounts of organic matter that are dissolved in water. In general, the total dissolved solids concentration is the sum of the cations (positively charged ions) and anions (negatively charged ions) in the water. Therefore, the total dissolved solids test provides a qualitative measure of the amount of dissolved ions.
Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). TDS is directly related to the purity and quality of water and water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic. During the brewing of coffee and espresso, solids are extracted from the coffee grounds and can therefore be measured with a TDS meter. Depending on Brew Temperature, Extraction Time, Grind Coarseness, Amount of Coffee etc., the TDS value measured will vary. The monitoring of the TDS value will ensure consistent product quality!
