LabSen 331 POM-body pH Electrode for Wastewater, Emulsions, Suspensions, BNC Connector

• Proprietary sensor technology and premium materials from Switzerland
• Open junction + Polymer electrolyte, ideal for testing wastewater, emulsions, and suspensions.
• Long-Life Reference System, improving the stability of reference system and extends the electrode's service life
• The blue gel electrolyte eliminates the chance of any air bubbles inside the sensor
• The POM electrode body is highly resistant to corrosion, ideal for use in harsh environments

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 331 POM-body pH Electrode is designed for testing wastewater, emulsions, suspensions, and other complex solutions that tend to cause junction clogs to regular pH electrodes.

Open junction + Polymer electrolyte - ensures full contact with test samples while eliminating junction clogs. No need for electrolyte refill.

Long-Life Reference System - 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 the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a 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 (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.
