pH is the concentration of hydrogen ions in the sample or solution, for the determination of alkalinity or acidity of the solution in the range of pH 01 to 14, the pH meter is used. The solution with more OH- stays alkaline while the solution with more H+ ions stays acidic.
The pH meter is used to determine the level of acidity in pharmaceuticals, food and beverages, water, mining, petrochemicals, chemicals and other industrial applications.
Advantages of the pH meter:
- This is a quick and easy process for measuring pH.
- This gives precise results and provides an accurate pH value.
- It is used for various types of applications.
- Covers the acid and alkaline pH range (pH 01 to 14).
- The user can calibrate it with the standard buffer solution (pH 07, pH 04 and pH 09.20).
- An added advantage of the pH meter is that it is portable.
- Compared to reading a color strip or a pH indicator, a pH meter provides very accurate results.
- A small, battery-powered meter is a great option when using it at a specific site.
Disadvantages of the pH meter:
- Deposits on the electrode membrane can disrupt processes.
- The pH meter is often necessary to calibrate it.
- A special buffer solution is needed to calibrate it.
- pH calibration can be influenced by temperature and carbon dioxide uptake.
- There is a risk of breakage due to brittle glass electrodes.
A pH meter is a device that determines whether a sample solution is acidic or alkaline. pH meters consist of a probe connected by a cable to a meter that displays the pH reading. In this pH determination technique, the electrical potential of pH-sensitive electrodes is used as the measurement signal.
