Digital pH Meter

Digital pH Meter A Digital pH meter is used to measure the acidity/alkalinity of a solution. The level of acidity/alkalinity is expressed as pH level, which generally ranges from 1 to 14. ?This pH measurement is directly related to the ratio of hydrogen ion concentration and hydroxyl ion concentration ([H+] and [OH?], respectively). The following are the pH levels: Neutral solution: pH = 7 Acidic solution: pH 7 A neutral solution will show a pH of 7 on a Digital pH meter due to the equal activities of hydrogen and hydroxide ions. Acidic solutions exhibit pH readings below 7 (higher hydrogen ion activity compared to hydroxide ion activity), and basic (or alkaline) solutions exhibit pH levels above 7 (hydroxide ion activity is greater than that of hydrogen ion). FEATURES of Digital pH Meter A Digital pH meter consists of three different parts: an internal electrode, a reference electrode, and a high input impedance meter. Glass probe often contains two electrodes ? an internal electrode and a reference electrode. Inside the probe is a buffer solution at a pH of 7. APPLICATIONS OF THE PH METER Digital pH meters are widely used in the following industries: Food & beverage Pharmaceutical Oil & gas Agriculture Water treatment plant This is not the total list of all of its areas of application.
