pH Electrode LabSen®331 POM APERA for Wastewater Treatment

The LabSen® 331 POM pH Electrode combines proven Swiss sensor technology and materials for reliable measurement in challenging wastewater treatment applications. The electrode features a unique blue hemispherical glass membrane that delivers faster response times, improved repeatability, and exceptional resistance to mechanical shock compared to traditional fragile glass bulb membranes. The solid polymer electrolyte operates in direct contact with test samples and withstands pressure up to 6 bar—ideal for suspension and wastewater testing. The long-life reference system employs a glass tube, AgCl, and reference silver wire, with cotton-filled top that prevents AgCl-electrolyte interaction during temperature fluctuations, extending electrode service life and reference stability. The BNC connector ensures compatibility with Apera Instruments pH meters including MP511, PH850, PH8500, PH700, PH910, PH950, PH820, and PC820. Built-in temperature sensor: No. Users must enable ATC or manual temperature compensation using a separate temperature probe (e.g., MP500).
