Purge Stabilization Flow Cell Overview

QED PurgeScan™ Technology provides an easier and more accurate assurance of purge stabilization

Successful, consistent low-flow ground water sampling is based on knowing when purge water indicator parameters stabilize. This ensures that sampling begins only when the samples are truly representative of water in the surrounding aquifer.

Until now, deciding when stabilization had been achieved was complex; it required you to monitor multiple ground water quality parameters simultaneously and make repeated calculations to determine whether the fluctuations in each parameter had fallen within acceptable limits. The MP20 Flow Cell changed this process forever. Microprocessor-based PurgeScan™ technology performs the monitoring and calculations automatically, clearly signaling when stabilization has occurred with audio and visual alerts.

This makes low-flow sampling easier, more accurate, and more efficient, too, as it frees your time to perform other sampling tasks while purging is underway. You can do it the right way, collecting the most accurate samples, and saving time and money.

Beyond its exclusive PurgeScan feature, The MP20 Flow Cell has been designed to continuously monitor groundwater quality parameters in-line, such as pH, temperature, redox potential, conductivity and turbidity (optional sensor) during purge.

The MicroPurge MP20 Flow Cell purge water quality monitor leads the field in performance, convenience, completeness and warranty. On top of all that, QED’s exclusive PurgeScan technology automatically signals when stabilization has been achieved for selected water quality parameters and stores key data points.

MP20 Advantages

  • Exclusive PurgeScan™ technology (U.S. Patent Number 6,415,659) automatically gives the OK to sample when selected purge water quality parameters remain steady over successive readings, at user-defined intervals.
  • Waterproof MP20 (U.S. Patent Number 6,415,659) meter displays all readings automatically: pH, ORP, temperature, conductivity, DO, and turbidity (optional).
  • Exclusive long-life pH electrode lowers maintenance costs significantly
  • Known for its exceptional ease of calibration
  • Fast PC download capability and automatic date/time stamping (MP20D and MP20DT models only)
  • Rugged, waterproof case doubles as a measurement and calibration workbench.
  • Transparent, molded flow cell effectively vents bubbles, even in the horizontal position; low internal volume (175 ml), designed flow distribution and built-in stirrer give fast response to changes in purge water quality, even at low-flow purge rates.
  • Exclusive Three Year Warranty.
