The Solinst Model 601 Standpipe Piezometer is designed to be placed within a drilled hole to provide a filtered inlet point. The pointed PVC tip is also suitable for pushing into very loose sands at the base of a borehole, a stream, or into very loose tailings pond sediments.
The 601 Standpipe Piezometer is excellent for metals sampling, as it is composed of a preformed Vyon tube set inside a perforated PVC piezometer tip.
The Model 601 is also well suited for water level monitoring, permeability measurements, air sparging, construction control, de-watering drainage operations, and slope stability investigations, etc.
The 601 Standpipe Piezometer connects to the surface with 3/4" Sch. 40 PVC (0.804" ID x 1.050" OD) plain end extensions, using slip couplings. Reducer couplings can also be used to connect to other sizes of riser pipe or casing.
The standard 601 Standpipe Piezometer lengths available are: 6", 1ft, 2ft and 3ft (15cm, 30cm, 60cm and 90cm). Solinst also offers the Model 615 stainless steel Drive-Point Piezometer, which is designed to be driven directly into the ground using a slide hammer.
Features:
Pointed PVC tip for pushing loose sands or backfilling within test pits
