QED MP20 | Multi-Parameter Flow Cells | Multi-Parameter Water Testing

The MicroPurge® basicsTM MP20 Flow Cell – from the leaders in low-flow ground water sampling – sets new standards in performance, size and price for purge water quality monitors. QED-exclusive PurgeScanTM technology (U.S. Patent No. 6,415,659) signals when stabilization has been achieved for selected water quality parameters, with automatic storage of key data points.

Two upgrades enhance performance even further. One option offers fast PC download capability. The other option also adds a technology breakthrough turbidity sensor in addition to pH, ORP, DO, temperature, and conductivity.

The lightweight, waterproof MP20 meter is simple to field calibrate. It displays all readings automatically. The sonde is a compact, low-profile design with rugged, easy-to-service probes. The flow cell is designed to collect and vent gas bubbles effectively, and to distribute purge flow evenly for quick measurement response and more accurate readings.

The whole package is protected by a 3-year warranty, backed by service and support from QED, the leader in low-flow sampling.

QED PurgeScanTM technology assures stabilization

Successful, consistent low-flow sampling is based on knowing when purge water indicator parameters stabilize. This allows sampling to begin only when the pump discharges samples representative of the formation water.

Until now, deciding when stabilization had been achieved was complex, requiring you to monitor multiple parameters and make repeated calculations. The MP20 Flow Cell simplifies this process. Microprocessor-based PurgeScanTM technology performs the monitoring and calculation, clearly signaling when stabilization has occurred.

This makes low-flow sampling easy. You can do it the right way, collecting the most accurate samples, and saving time and money.

Engineered for performance and field readiness

The MP20 flow cell is engineered to allow the probe to make rapid, accurate responses to changes in purge water parameters. The flow cell is 100% transparent for 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 so they don't interfere with 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 reference electrode is fully field-serviceable.

The large display screen makes it easy to see your purging status. Power by standard C cells keeps you on top of the job all day with no energy supply worries.
