A combination pH electrode that is used for measurement in polluted samples. It measures pH value of low-ion samples, the smallest of volumes, and much more. This pH electrode includes a polymer electrolyte and is a low maintenance and easy to clean electrode.

Key Features:

• Easy to clean split ring junction
• Polymer electrolyte which is maintenance free
• Built-in temperature sensor for automatic temperature compensation
