The Online pH Probe is designed for continuous, real - time monitoring of the pH value in various liquid processes. It uses advanced ion - selective electrode technology. As the probe is immersed in the flowing liquid stream, the electrodes detect the hydrogen ion activity and convert it into an electrical signal, which is then translated into a pH reading. This makes it invaluable in industrial applications such as chemical manufacturing, where maintaining a specific pH is critical for product quality and process efficiency. In environmental monitoring of rivers and lakes, it provides constant data on water acidity, helping to detect pollution events promptly. The probe is built to withstand harsh conditions, with corrosion - resistant materials protecting the electrodes. It offers high accuracy, often within ±0.01 pH units, and can be easily integrated into automated control systems. Its continuous operation mode allows for the detection of any sudden pH changes, ensuring process stability.
