4-20MA Digital pH Meter

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.
