Pure and Ultrapure Water pH Probes

pH probes and sensors have a difficult time measuring in low-conductivity water found in power plant cycle chemistry and microelectronics manufacturing applications. Until recently this required a measurement sensor, a reference sensor, a temperature sensor and a flow bowl. This is no longer necessary with the right selection of pure water pH electrodes.

Typical gel electrolyte pH probes are prone to error in low-conductivity water. While pressurized gel can reduce that error, a liquid flowing electrolyte is generally recognized to provide the most accurate measurement in pure water that has a low or very-low conductivity measurement.

These pure water pH sensors are installed in a low volume housing that prevents particles and sludge from accumulating and slowing down the response of the sensor. Additionally, buffer containers provide support for the electrode during buffer calibration. These combined with the fact that no external pressurization is needed, ensure easy maintenance for your pure water pH and ORP sensors.

Pure water pH sensors offer Intelligent Sensor Management (ISM) technology to help improve numerous day-to-day processes. For startup and calibration, sensors can be calibrated under lab conditions with calibration data stored in the sensor's connector. Then they can be transported out to the process where they can measure without any additional calibration. They also have a digital connection to reduce interference.
