Model 615 Drive-Point Piezometers have a stainless steel, 50 mesh cylindrical filter-screen (100 mesh for ML), within a 3/4" (20 mm) stainless steel drive-point body, screen support and an optional fitting for attachment of sample tubing.

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, even when inexpensive galvanized steel extensions are used.

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 in the hole.

The 615 ML Multilevel Drive-Point Ports have a dual barb stem to allow the connection of 3/8" OD (9.5 mm) or 1/4" OD (6 mm) tubing. The 615 ML uses the same couplings and extensions as the standard 615 Piezometers, but with a Drive-Point Tip to thread onto the first extension, or Port. Formation water enters the port, passes into the stem, and up into the monitoring tube attached to the stem to its static level. The 615 ML is also a good option for high resolution profiling of soil gas, or groundwater.

 

Stainless Steel Drive-Point Piezometers

Solinst Drive-Point Piezometers are available in five different configurations; the 615 with a barbed fitting, the 615 N with no barbed fitting, the 615 C with a compression fitting, the 615 S with a barbed fitting and shield, the 615 SN with a shield and no barbed fitting, and the 615 ML with a dual barb port stem.
