Digital Inclinometer System & Casing

Inclinometer System

Our Digital Inclinometer System is the most advanced traversing inclinometer on the market. Use it to measure lateral displacement of inclinometer casings in boreholes in soil and rock. Monitor movement of landslides, embankments, excavations, retaining walls, roadways, dams and tunnels. The system combines an iPAC Pocket PC as the readout unit, a waterproof stainless steel probe, and a low-stretch graduated cable.

The Pocket PC reads the probe over a Bluetooth™ wireless digital connection and is protected in a water-resistant case. The system includes a probe carrying case, cable reel with case, Pocket PC docking station, data collection software, battery charger, 12V automobile charging adapter, and spare battery. Also included are adaptors for use with 70mm (2.75 in) and 85 mm (3.34 in) inclinometer casing. Please specify cable length and wheel spacing, English (2 ft, Model 98067) or metric (500 mm, Model 98068), when ordering.

Software (GTILT)

GTILT is a Windows program that helps you handle any amount of traversing inclinometer data with a minimum of effort. It has powerful data plotting, archiving and manipulation features that enable you to extract the most information from your inclinometer surveys. Use GTILT to plot cumulative displacement, incremental displacement, and absolute position against depth or elevation. You also can plot displacement, shear strain, rate of displacement, and rate of shear strain against time. Make plots in the inclinometer groove directions or at a skew angle, in English or metric units. Correct for casing spiral using GTILT Plus. And you can view checksums in histogram form, allowing an immediate quantitative assessment data quality. GTILT exports Windows graphics metafiles (.WMF) for use with other applications. System requirements: Windows 98® or later.

GeoLok Inclinometer Casing

GEO-LOK Inclinometer Casing is preferred by drillers, geologists and geotechnical engineers because of its high strength and easy installation. Cumbersome couplings, glue, pop rivets, shear wires and tape are replaced with a threaded twist connection that is built onto each casing section and sealed with an O-ring. The fully detachable threaded coupling allows the casing to be retrieved and disconnected if necessary. And the casing joints are stronger than non-reversible snap-together designs! Install GEO-LOK casing vertically or horizontally, and then use our Little Dipper in-place inclinometer or Digital Inclinometer System to monitor ground movement. The most common applications are landslides, dam embankments, excavations, retaining walls, sheet piles, tunnels, landfills and tank foundations.

Telescoping Sections:
Outside Diameter 73 mm (2.87 in) and 89 mm (3.50 in)
