A pH sensor is a scientific device used to measure the activity of hydrogen ions in a solution, which is then expressed on pH meter. Measuring pH is a widely applied technique in various fields and ranges from laboratory measurements to process applications. With our pH measuring devices, one can also measure other important parameters like Conductivity, Ion Concentration, ORP, and Dissolved Oxygen.

The pH scale describes the acidity of the solution: acidic, neutral, or basic. A solution with a pH less than 7 is an acid, exactly 7 is a neutral solution, and above 7 is a base. Bases have fewer hydrogen ions but more hydroxide ions, represented by the pOH or "potential of hydroxide ions."

A pH meter measures the potential differences between a reference electrode (like Calomel or Ag/AgCl) and a pH electrode (glass electrode). This difference between the two electrodes is related to the concentration of H+ ions in the solution. Therefore, the difference in potential corresponds to the acidity / pH of the solution.

Applications include Agriculture, Food and Beverages, Water Analysis, Healthcare and Pharmaceutical, Paints and Dyestuff Industry, Cosmetics, Flavors and Fragrances, and Electroplating Industry.

Yes, calibration helps in determining that the instrument is functioning correctly. Calibration is necessary to adjust the slope and offset of a pH electrode to their true values for the measuring system in question. With routine calibration of the instrument, one can confidently do the measurements. pH meters are calibrated with appropriate laboratory calibration solutions of known pH. The frequency of calibration depends upon the frequency of the usage of the pH meter and its applications. For
