probe be cleaned and calibrated at least once every three months. Please refer to the appropriate sections

pH Monitoring (Optional)-
Ecowater has chosen to utilize an industrial pH probe for this measurement. A pH meter is an electronic
instrument used for measuring the pH (acidity or alkalinity) of a liquid. The pH probe measures pH as the
activity of hydrogen cations surrounding a thin-walled glass bulb at its tip. The probe produces a small
voltage (about 0.06 volt per pH unit) that is measured and displayed as pH units by the CHC Control
Station (CHCCS). The pH probe is a combination electrode, which combines both the glass and reference
electrodes into one body. It is important that this probe be clean and calibrated at regular intervals, please
refer to the appropriate sections of this manual for specific information.
