Semi-Micro pH Electrode for Samples (> 0.2 mL) LabSen®241-6 APERA

The LabSen®241-6 pH electrode utilizes a unique semi-micro cylindrical glass membrane (6 mm diameter) that simplifies small sample pH testing and enables measurement of high-temperature samples (up to 212°F). Equipped with a long-life reference system comprising AgCl and silver reference wire encased in a glass tube, with cotton filling at the tube opening to prevent chemical reaction between AgCl and electrolyte during temperature fluctuations. This design enhances reference electrode stability and extends overall electrode service life. The electrode features a BNC connector compatible with Apera Instruments pH meters including MP511, PH850, PH8500, PH700, PH910, PH950, PH820, and PC820. Note: No built-in temperature sensor. Users must employ either Automatic Temperature Compensation (ATC) or manual temperature input via separate temperature probe (such as MP500) for temperature compensation.
