What is pH Analyser?

pH analyser is a system that used for monitoring pH and consists of two main parts:

  • The meter/regulator
  • pH probe/pH electrode

Working Principles

A pH analyser works by detecting the change of pH through the pH probe (pH electrode). The change of pH will create a small voltage change that is then transmitted to the meter/regulator. After converting and calculating the generated pH/ORP signal according to the Nernst’S Law, the instrument will show the values on the screen.

Equation for pH:
