LabSen® 331 pH electrode for wastewater, emulsions and suspensions

SKU: 28APE190259 / AI3131 Categories: , , ,

Description

The LabSen® 331 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It is specially designed for the measurement of emulsions, suspensions, effluents, and samples containing proteins or sulfides. The solid electrolyte is extremely pressure resistant in combination with the hole diaphragm structure prevents the electrode from becoming clogged. A polyoxymethylene (POM) sheath serves as corrosion protection for the electrode and prevents possible damage from impacts.

Polymer electrolyte with hole diaphragm structure – Allows direct contact with test samples without clogging the diaphragm structure. The electrolyte does not need to be refilled.

LabSen S-Type Hemispherical Glass Diaphragm – Thanks to the low-resistance and rugged glass diaphragm, the electrode delivers fully stabilized readings in 15 to 30 seconds, yet is up to 10 times more rugged than conventional products, significantly reducing the likelihood of the electrode breaking during impacts.

Long-life reference system – The LabSen 331 pH electrode uses a long-life reference system consisting of a glass tube, AgCl and a reference silver wire. The top of the slim glass tube is filled with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the life of the electrode.

  • pH sensor technology and materials from Switzerland
  • Polymer electrolyte prevents clogging of the diaphragm
  • Blue gel electrolyte, does not flow and does not cause air bubbles
  • Long-life reference system that improves the stability of the reference electrode and extends the life of the electrode
  • The POM housing is highly resistant to corrosion

The electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. A temperature sensor is not integrated. For automatic temperature compensation, a separate temperature sensor (e.g. Apera Instruments MP500) is required, or the temperature must be entered manually.

This electrode has a 6-month manufacturer’s warranty.
