NEW! SP22 Groundwater Sampler


SP22 Stainless Steel and PVC Screens Available in 12- and 48-in. lengths	SP22 Screen Head 38657

The new Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen. The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-in. Lightweight Center Rods or PVC riser. The screen head adapts to either a stainless steel or PVC screen. Designed for tough probing conditions, the fully retrieveable sampler works well with the 8040DT machine or with 77- or 66 Series machines.

“Our clients are very satisfied with this new sampler. We’re pretty tough on tooling in this area because of the cobbles and gravels. We used 2.25 in. casing to sample to 126 feet, and had no sand in our samples. We plan to buy more!”
