The Innovative Sampling Systems Dual Range Bladder Pump Controller provides a bladder pump controller capable of purging and sampling wells with a head of up to 200 feet. The custom designed precision electronic timers allow accurate timing of each cycle component. The use of two separate pressure regulator circuits allow close control of the applied air pressure from 2 to 100 psi. Accessories are provided for charging the internal battery and connection to an external compressed air source. The controller can be used for both conventional and low flow sampling from monitoring wells.
