Advantages and Disadvantages of pH meter

Depending on the application, the pH meter provides several advantages in various sectors, which is mentioned in this article.

The 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 is having more OH- remains alkaline whereas the solution having more H+ ion remains acidic.

The pH meter is used for determining the acidity level in pharmaceuticals, food and beverage, water, mining, petrochemicals, chemicals, and further industrial applications.

Advantages of pH meter:

  • This is a fast and simple process of measurement of pH.
  • This gives accurate results and gives a precise pH value.
  • It is used for various types of applications.
  • It covers the acidic as well as an alkaline range of pH (pH 01 to 14).
  • The user can calibrate it with the standard buffer solution (pH 07, pH 04, and pH 09.20).
  • An additional advantage of the pH meter is that it is portable.
  • As compared to reading a color strip or a pH indicator, a pH meter provide very accurate results.
  • A small battery-powered meter is a great choice while you are using it in a specific location.

Disadvantages of pH meter:

  • Deposits on the electrode membrane can interrupt the processes.
  • The pH meter is often needed to calibrate.
  • A special buffer solution is required to calibrate it.
  • The pH calibration may be influenced by temperature and carbon dioxide absorption.
  • There is a possibility of breaking due to fragile glass electrodes.

A pH meter is an apparatus that determines whether a sample solution is acidic or alkaline. pH meters are made up of a probe linked by a wire to a meter that displays the pH reading. In this technique of pH determination, the electrical potential of pH-sensitive electrodes is used as a measuring signal.
