Apera 201DJ-C Double-Junction Combination pH Electrode is ideal for long time consistent testing in turbid water solutions, such as wastewater, pools and spas, and environmental monitoring. Its double-junction structure prevents the probe from being clogged and contaminated during measurement.
Compatible with any pH meters that use BNC connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to complete temperature compensation.
Not suitable for testing in low-ion concentration solutions (e.g.: deionized water or distilled water), strong base solutions (pH>12), highly corrosive liquid, or for continuous testing in high temperature solutions (> 60 °C/140 °F).
This electrode has a 6-Month limited warranty.
