The MicroPurge basicsTM MP10 Controller revolutionizes low-flow sampling with advanced logic control of purge flow and well drawdown. Simple up-down arrow keys increase and decrease purge flow, driving a microprocessor to re-create expert techniques for low-flow adjustment. Then, optimized settings are identified for recall in the next round of sampling. The MP10 also offers an easy way to prevent excessive monitoring well drawdown during purging, by linking to the optional MP30 Draw down/Water Level Meter.
