The HPW7000 combines a specially designed stainless steel flow chamber with a measuring/reference electrode system and integral temperature sensor/solution ground.
Its specially designed flow chamber optimizes the sample flow volume and creates the proper flow and mixing patterns to make the most accurate and stable pH measurement. The flow chamber cover is keyed and the electrode position is fixed so that the user continues to get the same superior measurement results every time a calibration or replacement is done.
A clamp mechanism holds the electrodes in place in the flow chamber, allowing quick and easy removal and reinstallation of the electrodes for calibration. It uses a flowing reference electrode to provide high accuracy and with minimal calibration offset errors.
