The QED MP20D flow cell is engineered to allow the sensing probes to make rapid, accurate responses to changes in purge water parameters. The flow cell is 100% transparent for ease of observation. The low-volume, fast-response cell couples to the sonde with a quick, bayonet attachment, and can be used in either a horizontal or vertical position. The incoming flow is directed in a tangential path around the flow cell to provide fast, thorough mixing with no 'dead spots' that could affect the accuracy of purge parameter measurements. Bubbles in the flow stream are vented out of the cell and away from the probe purge water analysis. The multiparameter probe has a special sensor with built-in stirring for highly stable dissolved oxygen readings. All sensors are easy to calibrate and the unique pH preferencce electrode is fully field-serviceable, a huge advantage in keeping field work on track as well as reducing pH probe replacement costs.
