Product Options


The Model 601 Standpipe Piezometer is designed to provide a filtered inlet point when it is placed within a drilled hole. Its pointed PVC tip makes it ideal for pushing into very loose sands at the base of a borehole, a stream or into loose tailings pond sediments.

It is composed of a pre-formed porous polyethylene tube set inside a perforated PVC Piezometer tip which makes it excellent for metals sampling. It is ideally suited for water level monitoring, de-watering drainage operations, permeability measurements, and construction control and slope stability investigations.

The Standpipe Piezometer tip connects to the surface with 3/4” ID PVC riser pipe using slip-fit couplings. It can also be used to connect to other sizes of riser pipe or casing if reducer couplings are used. The standard 601 lengths available are: 15 cm, 30 cm, 60 cm and 90 cm (6”, 1 ft, 2 ft and 3ft).

For applications with a need for the Piezometer to be pushed into the soil below the bottom of a borehole, Solinst offer the Model 615 stainless steel Drive-Point Piezometer. This can also be driven directly into the ground from the surface.

For monitoring water levels:

  • 102 Water Level Meters with 10mm Probe
  • A 1” to ¾” stainless steel reducer coupling to install a Levelogger in a 1” drive extension section.

Sampling options include:

  • 410 Peristatic pump
  • 403 Mini inertial pump
  • Narrow diameter 429 Point-Source Bailer
The 601 and 615 are designed for permanent monitoring. So, neither are reusable, but the 615 can pulled out mechanically. However, grouting is the most favourable method of decommission on both of these pieces of equipment. The 660 Drive-point Profiler is a short-term monitoring point, therefore the hole left behind can be easily grouted using a grout tip Drive-point profiler.
The depth that these can be installed to depends on the material in which they are being installed in. Typically, you will get a deeper installation in peat over other ground materials.
