The Model 4435 Soil Extensometer is designed to be installed, in series, to measure horizontal strain and settlements in earthfill or rockfill dams. The 4435 has flanges on either end, which enable a series of extensometers to be bolted together forming long strings of sensors so that complete profiles of deformation or settlement can be monitored.

The Model 4430 Deformation Meter with flanged ends is designed to measure longitudinal deformation in dams and embankments. It can also be grouted or held in place by hydraulic anchors to measure deformations in boreholes (over the gage length). Gage lengths from 0.5 to 100 meters are available.

The Model 4422 is a miniature crackmeter intended to measure displacements across surface cracks and joints. It has been specially designed for applications where access is limited and/or where monitoring instrumentation is to be as unobtrusive as possible (e.g. on historical structures or buildings).

The Model 4400 Embedment Jointmeter is designed for use across construction joints, such as those between adjacent blocks in a concrete dam. It is normally embedded across the joint to monitor the expansion or contraction of the joint. The use of internal universal joints allows for a degree of shearing motion.

The Model 1900 Magnetic Extensometer is designed to measure settlement or heave of soft ground under the influence of loading or unloading due to the construction of embankments, fills, buildings, foundations, and structures. A probe is lowered inside a telescoping guide tube to detect and measure the position of magnetic anchors located around the guide tube at various depths along the borehole or within the fill. Plate anchors are used in fill and spider anchors in boreholes.

The Model A-9 Retrievable Extensometer (Patent No. 5, 585, 555) is designed to measure deformations in boreholes in rock, concrete, and other construction materials. The device can be used in pile load test studies, plate jacking tests and virtually any application where a hole can be drilled or a pipe can be cast into the structure being studied. The system features adjustable gage lengths, rapid and simple installation/removal and high accuracy using a variety of transducers including Vibrating Wire and DCDTs. Adapters for use in square tubing are also available.

The Solinst Model 101 Water Level Meter is available in several versions and is considered the industry standard for portable, hand-operated measurement of water depth in wells, boreholes, standpipes and tanks. They are sturdy, easy to use and provide accurate results to the millimeter, or to 1/100 ft.

The Model 101 Water Level Meters feature pressure-proof stainless steel probes rated to 500 psi, laser marked PVDF tapes, indicator lights and audible alarms.

Drive Point Piezometer has the transducer located inside a housing with an EW drill rod thread and removable pointed nose cone. This model is ideally suited for use in peat and soft clays. The piezometer may be recovered at the end of the job. Models are also available which use metric threads allowing for installation using conventional cone penetrometer or other drill rods with adapters.

The Model 4500MLP system overcomes the problems associated with the installation of multiple piezometers in a single drill hole. The 4500MLP is lowered into position and a spring loaded apparatus is actuated forcing specially configured piezometer filter elements into firm contact with the borehole walls. The borehole is then grouted from the bottom in one quick and simple operation.
