Digital pH meter

  1. 1. Digital pH meter Presented By: Arpan Bose Roll no: 1830166 Date: Subject:PMI
  2. 2. • A pH meter is an electronic device used for measuring the ph(acidity of alkanity) of a liquid (or semi solids substances using special probles) • A typical pH meter consists of a special measuring probe(a glass electrode) connected to an electonic meter that measures and displays the pH reading
  3. 3. • The probe is a rod like structure usually made up of glass • At the bottom of the probe is a bulb,the bulb is the sensitive part of the probe that contains the sensor • To measure the pH of a solution the probe is dipped into the solution The probe
  4. 4. • A pH meter measures the concentration of the hydrogen ions[H+] in a solution • An acidic solution has greater potential to produce an electric current under certain conditions • It consists of a pair of electrode connected to a meter capable of measuring small voltages. Working
  5. 5. • It measures the voltage produced by the solution whose acidity is to be found,compares it with the voltage of a known standard solution and uses the difference in voltage between them to calculate the difference in pH
