Solinst Model 615 Shielded Stainless Steel Piezometer

Key Features

• Affordable method to monitor shallow groundwater and soil vapor
• Attach to inexpensive 3/4" (20 mm) NPT steel drive pipe
• Can be used for permanent well points or short-term monitoring applications

Overview
The Solinst Model 615S shielded drive-point piezometer uses a high-quality stainless steel piezometer tip, 3/4" NPT pipe for drive extensions and LDPE or Teflon sample tubing, if desired. Combine these with an inexpensive Slide Hammer to create a complete system.

Design
The Solinst Model 615S shielded 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 a barbed fitting for attachment of sample tubing. Optional heavy-duty extension couplings are also available to create a strengthened and more rugged piezometer. The inner barbed fitting allows connection of 5/8" OD x 1/2" ID (16 mm x 12 mm) LDPE or Teflon sample tubing. This prevents sample water from contacting the steel extension rods, and maintains high sample integrity, even when inexpensive carbon steel extensions are used.
