WATER SAMPLER The Geocontrol PRO is a compact and portable controller, weighing less than 8 lbs. It will control all portable bladder pumps, dedicated bladder pumps, and most air lift pumps on the market today, operating from a rechargeable 12 VDC battery. The ultra-reliable mini-compressor inside allows the user to sample from depths to 200′, saving you time and money from using a separate air compressor. The Geocontrol PRO features a push/pull tubing fitting for easy tubing changes, and Polyethylene or FEP tubing is available per foot. Geotech’s portable bladder pumps were designed with input from field technicians who actually do the sampling. Single-turn release heads and quick-change bladders have been incorporated for quick in the field bladder changes and easy decontamination. Custom hose barbs allow the pump to be suspended without the need for tubing clamps.
