Solinst Modell 615 Drive-Point Poretrykksmålere

Solinst Modell 615 drive-point poretrykksmåler er et rimelig alternativ for overvåkning av grunnvann og jordfuktighet i mindre krevende miljø. De tilgjengelige modellene tillater vannstandsmålinger eller pumping av vannprøver gjennom et slangesystem.

  • Utstyrt med rustfri ståltupp av høy kvalitet
  • Enkel nedpressing ved hjelp av håndholdt verktøy
  • Metoden tåler opptil 7,5m i egnede jordarter



The Model 615 Drive-Point Piezometer is designed as an affordable method to monitor shallow groundwater and soil vapor in suitable conditions.

The Drive-Points attach to inexpensive 3/4" (20 mm) NPT stainless steel drive pipe. The Drive-Points are designed for single use installations, and not for removal and reuse. Solinst Drive-Point Piezometers are most often installed as permanent well points. They can also be used for temporary, short term monitoring applications.

Higher quality samples can be obtained when polyethylene or PTFE-lined tubing is attached to the stainless steel drive-point. Groundwater sampling and hydraulic head measurements can be taken within the tubing using small diameter equipment, as described below.

Solinst Drive-Point Piezometers can be driven into the ground with any direct push or drilling technology, including a manual slide hammer. To avoid clogging or smearing of the screen during installation, a shielded version is also available (615S and 615SN).


  • Model 615: The 615 Drive-Point Piezometer 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.
  • Model 615N & 615SN: 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.
  • Model 615 & 615S: 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.
  • Model 615C: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" (6 mm) sample tubing directly to the top of the screened portion of the drive-point.
  • Model 615S & 615SN: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.
