OVERVIEW
Avoid drops in performance
The D-phi Series reference solution becomes diluted over time by the sample. If excess dilution occurs, then sensor drift occurs and more frequent calibration is required. To avoid drops in performance, we recommend replacing the reference solution every 1-2 months. Ideal replacement frequency depends on the application and must be determined empirically through calibration checks. Applications with high flow rate, temperature, pressure, alkalinity, or acidity dilute the reference faster and may require more frequent replacement.
The D-phi Series Reference Refil kit is compatible with the D-phi Series 4-20 mA Differential pH Sensors and the D-phi Series 4-20 mA Differential ORP Sensors.
Watch the video in the gallery above to see how easy the 60-second reference replacement procedure is.
