The new MicroPurge® MP25 Flow Cell system makes consistent low flow ground water sampling easy and accurate. Exclusive PurgeScan™ technology monitors purging parameter and performs the stabilisation automatically. PurgeScan Android based software compares readings with previously recorded values, determining when they fall within user-defined criteria. The included Trending function makes sure purging parameters aren’t moving upward or downward in a distinct trend, helping to avoid “false stabilisation” and assure that purging is truly completed, as defined in ASTM Standard D6771-18. The MicroPurge® MP25 Flow Cell system measures electrical conductivity (specific conductance), pH, ORP, dissolved oxygen and temperature and calculated values such as total dissolved solids (TDS), salinity and oxygen saturation; the MP25T system adds turbidity measurement. Sensor calibration is fast and easy and the sensors are highly stable, so calibration holds under use. The multi-parameter sonde connects wirelessly to most Android tablets and smart phones using a long-life rechargeable Bluetooth battery pack. Housed in a rugged, waterproof case that doubles as a measurement and calibration workbench in the field, the system includes: multi-parameter sonde and flow cell, Bluetooth battery pack, 3m waterproof cable, sensor guard and calibration/storage cup, field calibration stand, a range of quick-connect barb fittings to fit most common pump discharge tubing sizes, flexible flow cell tubing and sensor solutions for DO and reference sensors (calibration standard solutions are sold separately).
