Description

The Solinst 615 Drive-Point Piezometer is designed as an affordable method to monitor shallow groundwater and soil vapor in suitable conditions. It has a stainless steel, 50 mesh cylindrical filter-screen, within a 3/4″ (20 mm) stainless steel drive-point body, screen support and an optional fitting for attachment of sample tubing.

Applications
– High-resolution vertical profiling
– Groundwater sampling, including VOCs
– Water level monitoring
– Base flow monitoring in stream beds
– Contaminant plume delineations
– Soil gas sampling
– UST monitoring
– Low cost and minimal disturbance site assessment
– Sparge points

The 615 N or 615 SN, designed without a tubing barb, is to be used for water level measurements. This saves money and provides better access for Water Level Meters.

The 615 or 615 S has an inner barbed fitting for 5/8″ OD x 1/2″ ID (16 mm x 12 mm) LDPE or PTFE-lined sample tubing. This prevents sample water from contacting the extension rods and maintains high sample integrity.

The 615 C is ideal for soil vapor sampling. Where an air-tight connection is most desirable, the compression fitting option allows users to attach 1/4″ OD (6 mm) sample tubing directly to the top of the screened portion of the drive-point.

The 615 S and 615 SN shielded drive-points have a single use, 1-1/2″ (38 mm) dia. shield to avoid smearing and plugging of the screen during installation. The strengthened connector at the top of the drive-point acts as an annular seal, which avoids contamination from higher levels.

Solinst 615 Drive-Point Piezometers can be driven into the ground with any direct push or drilling technology, including the Manual Slide Hammer.
