What is pH Analyzer?

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

  • The meter/regulator
  • A probe/measuring electrode

Working Principles

A weak voltage change is generated when  affects the inserted sensor, the changeable value will transmit to the instrument. 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:
