Apera Instruments AI3115 pH Electrode (Double-Junction, BNC Connector)

Features:

• 201DJ-C Double-Junction pH Electrode is built with Apera's proprietary lithium glass membrane and double-junction structure, which can reduce junction clogs and extend the electrode's service life for long-term testing in turbid and complex water solutions such as wastewater, pools, environmental monitoring, and etc. 
• Standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is 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 (eg: deionized water or distilled water), strong base solutions (pH>12.00), strong acid solutions (pH<2.00), highly corrosive solutions, or for continuous testing in high-temperature solutions.
