MP30 MicroPurge Drawdown and Water Level Meter

Prevents Excessive Drawdown During Low Flow Groundwater Sampling. 

Limiting drawdown is one of the basic requirements of proper low-flow sampling. The MicroPurge® MP30 (U.S. Patent Number 6,456,201) Drawdown/Water Level Meter provides a unique and simpler way to assure proper drawdown control.
The MP30 switches between two modes- as a drawdown sensor and control when connected to the MicroPurge basics controllers, and as a high quality water level meter.
