FAQ

FAQ of  measurement accuracy  test digital water pH value Meter

1.What is a pH meter?
A pH meter is an scientific device used to measure the activity of hydrogen ions in a solution, which is then expressed as pH. 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. This page showcases the types of laboratory pH meters and their applications.

2.What's the The pH Scale: Acidic, Neutral, and Basic?
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."

3.How does a digital pH meter work?
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.

4.What are the different applications of a pH measurement instrument?
Agriculture,Food and Beverages,Water Analysis,Healthcare and Pharmaceutical,Paints and Dyestuff Industry,Cosmetics, Flavors and Fragrances,Electroplating Industry

5.Is it necessary to calibrate the pH meter? How to better perform a calibration?
Yes, calibration helps in determining that the instrument is functioning correctly. Calibration is necessary to adjust the slope and offset of an 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 applications. For details please refer to user manual of BOQU Instrument.

6.Does BOQU Instrument support installation qualification?
Yes,we offer professional installation, qualification and calibration services. These services will guarantee accurate and precise measurements making the user worry-free when it comes to possible compliance issues during quality audits.
