The food pH electrode is designed for pH measurements in water and other liquids, especially in small-volume samples. The electrode can also be used as a universal pH sensor under laboratory conditions. The food pH electrode has a glass body and is equipped with a ceramic diaphragm.

The conical shape of the diaphragm and the easy accessibility of the contact point make cleaning the food pH electrode very easy. The small diameter of the food pH electrode and the shape enable measurements in samples with a small volume in test tubes or other small vessels. There is an opening in the food pH electrode for refilling or replacing the reference electrolyte.
