LabSen 211 Glass-body pH Electrode for General Water Solutions, TRIS Buffer compatible, BNC Connector

Product Description

• Proprietary sensor technology and premium materials from Switzerland
• Built with LabSen S-type hemispherical glass membrane, featuring low resistance (fast response) and high firmness
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.
• Long-Life Reference System improves the stability of reference electrode and extends the service life of the electrode
• Compatible with TRIS buffers

Built with proprietary sensor technology and materials from Switzerland, Apera LabSen 211 pH Electrode is ideal for professional lab and field pH measurement of general water solutions.

LabSen S-type hemispherical glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage.

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 reference electrode and extends the service life of the electrode.

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 MP500) to enable ATC or manually input temperature to achieve temperature compensation.
