The RST Convergence Monitor is an economical, robust instrument for the continuous or random monitoring of ground closure in mining and civil engineering projects.
Crack Meters are designed to measure movement across surface cracks and joints. Crack Meters are available in 3 versions: 3-D Crack Meters, Vibrating Wire Crack Meters and Electrical Crack Meters.
Flexible Rod Extensometer
Flexible Rod Extensometers are a low cost, convenient instrument for the monitoring of ground displacements. Designed to withstand severe field conditions and accommodate transverse shear.
Laser Distance Meter
The Laser Distance Meter is a portable device designed to measure distances from the device to a remote target point located up to 500 meters distant.
Rod Extensometer Single and Double Point
The Single Point Rod Extensometer is an inexpensive, simple, rugged, and reliable device to monitor deformation in under ground workings. The Double Point Extensometer incorporates the use of two points which allows the engineer to distinguish between dangerous deep seated movements and more trivial surficial spalling.
Rod type Multiple Point Borehole Extensometer
Multiple Point Borehole Extensometers measure the stability and movement behavior of soil and rock masses.
The RST Vibrating Wire Soil Extensometer is developed to monitor lateral and longitudinal deformation of soil and different types of embankments and embankment dams.
The RST Tape Extensometer is a portable device, designed to measure the relative distance between reference anchors fixed to the excavation or structure.
Tell Tale Crack Meters
Tell Tale Crack Monitors measure displacement (out of plane) and movement across a crack.
Tunnel Profile Monitoring System
The Tunnel Profile Monitoring System is a series of linked rods, fixed to the tunnel wall, to monitor deformation. A data logging system and related software is available to provide near real time displacement and generate a graphical representation of tunnel performance.
Vibrating Wire Joint Meter
The RST Vibrating Wire Joint Meter is developed to monitor joints of mass concrete structures.
