Light Falling Weight Deflectometer
INSPECTOR-4 is a portable falling weight deflectometer (LWD) for measuring the ground elastic modulus, maximum deformation, compaction factor, elastic deflection and deformation time. It is ideal for testing in regular or difficult to access areas.
The deflectometer can be used in design, construction, maintenance and quality control of buildings, subdivisions, roads, railways and other environments to measure elastic modulus of unbound or partially bound material, including asphalt, granular aggregation base, base layers, soil, concrete etc.
INSPECTOR-4 is portable, compact and can easily be used by a single operator. The device’s intelligent built-in electronic unit calculates and displays the results immediately after the series of measurements is completed. All measured data is stored and can be downloaded to a computer via USB or Bluetooth connection. The results can also be read to the user’s mobile phone and forwarded via e-mail to off-site staff for real-time verification against expected results.
A separate GPS unit is available to determine and store the exact location of the measurement, which can later be graphically displayed in Google Maps.
