LabSen®881 Professional Combination pH Electrode for Low Temperature...
The picture may be different from the article and can include supply, which is not in the standard scope.
The LabSen® 881 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It was specially developed for measuring low-temperature solutions (down to -30 °C). LabSen L-type glass membrane - The electrode has a special conical glass membrane that is up to 10 times more robust than conventional products and is particularly suitable for low-temperature solutions (down to -30 °C) due to its very low resistance (<50MΩ). Silver ion trap reference system + protelyte electrolyte - The LabSen 881 pH electrode is equipped with a silver ion trap reference system and a protelyte reference solution. In addition to the long-life reference system, a silver ion trap is incorporated to prevent blockage or contamination of the diaphragm and increase the life of the electrode.
Technical Specifications:
This electrode has a 6-month manufacturer's warranty.
