pH Measurement (pH)
pH 722 Z1-Gel / Z3-Gel pH Probe
Low-maintenance pH probe with electrolyte gel and excellent measurement performance.
The Z1-Gel with 1 diaphragm is suitable for lightly polluted water. The Z3-Gel has 3 diaphragms and is well-suited for long-term use in heavily polluted water.
Advantages
Method
The pH-sensitive part of the pH probe is the membrane glass. This glass reacts on hydrogen ions in solution with high selectivity and sensitivity. Depending on the concentration of hydrogen ions the voltage output of the pH probe changes, which is then converted into the pH value by the measuring transducer.
Applications
- Drinking water
- Process water
