pH Meter

A pH meter is a device used to measure the acidity or alkalinity of a solution – also known as pH. pH is a measurement of acidity or alkalinity. It is measured on a scale of 0 to 14 points. The amount of information provided by the pH value indicates the acidic or basic activity of the hydrogen ion. The pH value of a substance is directly related to the concentration of hydrogen ions [H+] and hydroxyl ions [OH-]. When the concentration of H+ exceeds the concentration of OH-, the substance is acidic; That is, the pH value is less than 7. If the OH- concentration is greater than H+, the substance is basic, with a pH value greater than 7. If H+ and OH- ions are present in equal amounts, the substance is neutral, and The pH is 7. Acids and bases Free hydrogen -form hydroxyl ions. The relationship between hydrogen ions and hydroxyl ions in any compound is constant for a given set of conditions and can be determined by analyzing one or the other. The working principle of the pH meter is based on the exchange of ions from the sample solution through the glass solution to the inner solution (pH 7 buffer) of the glass electrode. A pH probe consists of two electrodes, namely a sensor electrode and a reference electrode. One is filled with pH 7 buffer, and the other with a full potassium chloride solution. The sensor electrode bulb comprises a perforated glass coated with metal salt and silica.

The Key Features of the pH Meter are as follows :

• Accurate pH measurement
• Broad views
• Easy-to-use interface
• Portable and compact design
• Measurement and maintenance work
