The Apera 201DJ-C Double-Junction Combination pH Electrode is ideal for long duration testing in turbid water solutions such as wastewater, swimming pools and spas, and for environmental monitoring.
Due to its double diaphragm structure, the electrode is prevented from becoming clogged and contaminated during measurement.
Not suitable for measurements in solutions with low ion concentration (e.g.: deionized water or distilled water), strongly basic solutions (pH>12), highly corrosive liquids, or for long-term measurements in solutions with high temperature (>60°C).
Compatible with all pH meters with BNC connectors. The temperature sensor is not installed. For full temperature compensation, a separate temperature probe is required to activate ATC or enter the temperature manually.
The electrode has a 6-month manufacturer’s warranty.
