Apera Instruments AI3109 Glass-Body pH Electrode for Strong Acid Samples and HF (Hydrofluoric) Acid

Features:

• Proprietary pH sensor technology and premium materials from Switzerland
• LabSen HF glass membrane designed for accurate measurement in strong acid samples, and is resistant to hydrofluoric corrosion
• Silver Ion Trap Reference System
• LabSen's sturdy glass membrane is 10 times stronger than traditional glass membranes
• The blue gel electrolyte eliminates the chance of any air bubbles inside the sensor
• Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 831 HF pH Electrode is designed for professional pH measurement of solutions containing HF (Hydrofluoric) acid, and other strong acidic solutions.
• LabSen HF glass membrane -- designed for accurate measurement in strong acid samples, and is resistant to hydrofluoric corrosion, good for 1000 times of measurement (measurement time<1 minute, and HF concentration should be less than 0.1mol/L or 0.2% wt%)
• Built tough -- The hemispherical glass membrane is 10 times stronger than traditional glass membranes, and highly resistant to general impact, saving the electrode from accidental damage.
• Silver Ion Trap Reference System -- On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clogs.
• The electrode uses a 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 to enable ATC or manually input temperature to realize temperature compensation.
