The standard 615 has a 5/8″ OD barbed fitting that allows a sample tube to be attached for obtaining groundwater samples. The standard 615 has a 5/8″ OD barbed fitting that allows a sample tube to be attached for obtaining groundwater samples. The 615 C provides an airtight connection with a 1/4″ compression fitting, ideal for vapour sampling. The 615 N, designed without a tubing barb, is most ideal for water level measurements using Water Level Meters. To ensure that the screen does not clog or smear, 615 S shielded versions are available for sites with high silt or clay content.

615 ML Multilevel Drive-Points have a barbed port stem to allow the connection of 3/8″OD or 1/4″ OD tubing. They allow multilevel monitoring for up to 6 zones in one drive. Water from the monitoring zone enters the port, passes into the stem, and up the attached tubing to static level. The 615 ML is ideal for high-resolution vertical profiling of soil gas or groundwater.

The Standpipe Piezometer is primarily used to provide a filtered inlet point when backfilled in place within a pre-drilled hole or test pit. The pointed tip can also be pushed into very loose sands at the base of a borehole, stream, or into loose tailings pond sediments.. Standpipe Piezometers are great for water level monitoring, permeability measurements, slope stability investigation, dewatering operations, air sparging and metals sampling.
