Online pH Meter for pure water

Online pH meters for pure water measure the concentration of hydrogen ions in water using a glass electrode and a reference electrode, converting the resulting potential difference into a pH value. They are used to monitor changes in the acidity or alkalinity of pure water systems, preventing equipment corrosion or scaling. They are commonly employed in boiler feedwater and for monitoring ultrapure water in the electronics industry.
Selection
When selecting, focus on electrode materials that are resistant to low-conductivity pure water environments. The instrument should have temperature compensation and signal stabilization functions. Consider compatibility with installation methods and pipelines, ensure calibration cycles align with actual usage frequency, and confirm the protection rating is suitable for the site environment.
