In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. With the Schmidt + Haensch on-line process Titrator the continuous analysis of the pH value and alkalinity during the purification of the raw sugar juices is made simple and reliable. Your process will be optimized, saving resources and auxiliary materials while all important process parameters are being controlled .
