Insufficiency in the performance of commercial Ag/AgCl reference electrode have been demonstrated in pH measurements on diluted standard buffer solutions. To improve the performance of Ag/AgCl electrode, electrochemical method which controls voltage in forming AgCl on silver was used and AgCl deposition conditions were optimized for each factor. For the purpose of increasing its long term stability, heating and polymer containing chlorine ions were treated. Then, they were packaged as reference electrode and applied to pH sensor as innner reference electrode of pH glass+ electrode. The fabricated Ag/AgCl reference electrode showed good performance. Also, combined pH sensor using Ag/AgCl reference electrode showed good performance and made pH measurements possible.
