Hydrogen Platinum pH Electrode pHydrunio
The world's first platinum-hydrogen pH electrode for sale (Patent DE 10 2011 113941).
pH Electrode pHydrunio
pHydrunio is the logical further development of our mini platinum hydrogen electrode Mini-HydroFlex. It combines a reversible platinum hydrogen electrode as the measuring electrode with a platinum hydrogen reference electrode in an interior electrolyte (pH 7) as the reference electrode. It is delivered activated and supplied with hydrogen gas by an internal supply for 12 months. Then, the hydrogen cells can be replaced.
The hydrogen inside the shaft ensures the controlled electrolyte output out of the diaphragm. However, if measuring solution enters the electrode, the interior electrolyte can be replaced.
pHydrunio is made of polypropylene and is therefore indestructible. Thus, it can be used in highly alkaline or acid electrolytes as well as in concentrated fluoride media.
The shaft is 120 mm long and the diameter is 12.2 mm. A PG 13.5 thread enables the installation in appropriate armatures.
The measuring electrode is protected from mechanical damages by a protective sleeve.
pHydrunio can be connected to any pH meter with analogue input (BNC or open wire ends).
In contrast to conventional glass electrodes, our hydrogen pH electrode has a low resistance.

Principles of the pH-value Measurement with Hydrogen Electrodes
The hydrogen potential directly depends on the activity or rather the concentration of the hydronium ions and thus on the pH-value of the solution.
