Geoprobe® SP16 Groundwater Sampling - Step by Step

[@ASaltyyDog]

Can you tell me the difference between the SP16 and SP19 groundwater samplers?

The SP19 would primarily be used with 1.75” rods so the outer sheath is a little thicker/larger as well. That’s the primary difference between the two. There is a little more information here: geoprobe.com/tooling/sp19-groundwater-sampler
