There are two hemispheric structures inside the pH electrode: one hemisphere contains a reference solution with a certain concentration of hydrogen ions, and the other is placed at the bottom of the electrode and is a glass semipermeable membrane that is only sensitive to hydrogen ions. The potential difference between the two hemispheres is the output voltage of the electrode, which varies because the glass semipermeable membrane is immersed in solutions with different hydrogen ion concentrations. Therefore, the pH electrode actually converts the pH information of the measured solution into a voltage signal, which is then processed by an electrical signal amplifier and a trimmer in the sensor, and is adjusted to a voltage of 0-5 volts and input to the data collector in the analog-to-digital converter. The collector’s memory will hold this data in a suitable format.

All experiments or demonstrations using traditional pH meters can use our pH sensors. Using this sensor, you can automatically collect data, make charts through software, perform data analysis and processing, etc. Its typical applications are: studying common household acids and bases, acid-base titrations, the effects of buffer solutions, etc.
