LabSen® 231 Combination pH Electrode for Wastewater, Suspension, and Emulsion Backed by proprietary Swiss sensor technology and materials, the LabSen 231 Combination pH Electrode is ideal for testing emulsion, suspension, wastewater, and samples containing protein and sulfide. Its 2-pore double junction structure and solid electrolyte make it hard to be contaminated and highly resistant to compression. Long-Life Reference System – The LabSen 231 pH electrode adopts a long-life reference system, which is composed of a glass tube, AgCl and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when temperature changes. It improves the stability of reference electrode and prolong the service life of the electrode. Polymer Electrolyte – The polymer electrolyte is in direct contact with test samples. The anti-pressure capacity can reach up to 6 bars, making it ideal for testing suspension and wastewater. Special Glass Membrane – The LabSen 231 pH electrode adopts a Half-Balll glass membrane, which is highly resistent to general impact (the traditional glass bulb membrane is a lot more fragile), and can be tested in high temperature samples (up to 176°F). The electrode is backed up with a 6-month warranty by Apera Instruments. Learn More

LabSen unique blue hemispherical glass membrane – faster response time, better repeatability, and built tough, highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane); and can be tested in high temperature samples (up to 225°F). The LabSen 211 Combination pH Electrode Sensor adopts a Long-Life Reference System, which is composed of a glass tube, AgCl and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when temperature changes. It improves the stability of reference electrode and prolong the service life of the electrode. The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera's MP511, SX811, PH700, PH800, PC800, PH820 and PC820. Temperature sensor is not built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation. The electrode is backed up with a 6-month warranty fulfilled byApera Instruments. Learn More
