Aqua3700HF Hydrofluoric Acid Glass pH Electrode
Summary:
The Aqua3700HF pH electrode features a unique hydrofluoric-acid-resistant glass sensing membrane that differs from conventional hydrofluoric-acid-resistant glass, offering superior resistance to hydrofluoric acid corrosion and significantly extending the electrode’s service life. It can withstand hydrofluoric acid concentrations of up to 5,000 ppm—far exceeding the tolerance levels of comparable imported products—and delivers superior measurement accuracy and faster response compared with antimony-based electrodes. As a result, it is highly favored by customers in industries such as semiconductors, petrochemicals, steel mill wastewater treatment, and metal processing.
