Digital pH Meter with 4-20MA Output

Construction of pH meter:
pH sensor or probe of modern pH meter combined type, in which test and reference electrodes placed into a glass tube-like structure. The combined electrode consist of following parts-

design and Construction of pH meter Probe

1. Glass bulb: The sensor that senses the H+ ion concentration made from a special type of glass and membrane. The glass bulb consists of 0.1M HCL Solution.
2. Internal electrode: This electrode made by silver chloride.
3. Internal solution: The silver chloride electrode, dipped in a buffer solution of 0.1 mol/L KCL of pH 4 to pH 7.
4. Reference Electrode: It also the silver chloride electrode used for reference.

5.Junction: It made from a ceramic junction also called a diaphragm that allows the contact of sample solution and reference electrolyte. It should not disturb the electric connection between both electrodes.
6. Filling hole: This used for refilling the electrolyte if required.
7. Electrode body: Electrode body Made from non-conductive glass, plastic material and may coated by epoxy to prevent glass bulbs.
