Light Weight Deflectometer
Lightweight Deflectometer – buy for best price!
Light Weight Deflectometer for dynamic plate load test is a light weight portable device to measure the bearing capacity of subgrade and subsoils. It is a perfect tool to determine the compaction quality of unbound base layers, granular layers and backfill material in earthworks and road constructions. Using TERRATEST® LWD is the easy and fast way to check quality of soil compaction in construction sites. One single person needs only two minutes to perform the test, no load vehicle as counterweight is needed.
Lightweight Deflectometer of TERRATEST® is fully equipped with GPS system, printer, high-performance rechargeable battery and PC-software. The Light Weight Deflectometer speakes and navigates the user through the test procedure.

CABLE or BLUETOOTH:
We offer both models
Light Falling Weight Deflectometer TERRATEST 6000 BLE offers a reliable data transfer, quick pairing and extremely powerful rechargeable battery. You can perform up to 2000 tests or 600 printouts with the powerbattery.
TERRATEST 6000 BLE is particularly suitable to perform many tests in large area. Repairs of the socket of the load plate or of the measurement electronics – the typical “Achilles’ heel” of the device – will no longer be necessary thanks to its wireless operation. NO WIRES, NO PROBLEM!
The socket of the load plate has always been the Achilles’ heel of traditional Light Weight Deflectometer with wire connection. Throughout the entire life (15 years) of a Light Weight Deflectometer, the measuring cable has to be plugged into the load plate on the ground every time a test is being conducted. The forces that arise during the measuring process strain the sockets and cables over time. The conditions in a utility trench and road construction are generally an adverse environment for wires and sockets.
That’s why experts are choosing our Light Weight Deflectometer TERRATEST 6000 BLE for dynamic load plate tests!
For different overseas standards TERRATEST® produces the TERRATEST 9000 LWD Light Weight Deflectometer according to ASTM E2583-07. This device works with a central geophone and an integrated load cell.
Light Weight Deflectometer Perfect in pipeline construction
Light Weight Deflectometer is the best tool for compaction test in hard to reach places such as backfill in trenches. Most requested is the TERRATEST® Bluetooth model for this application, because user can connect the load plate of the Light Weight Deflectometer directly to their own smartphone. The measuring computer is not needed anymore for test procedure.
Lightweight Deflectometer: FunctionalityLight Weight Deflectometer is the ideal equipment for construction companies to check the compaction quality of soil. It is used in earthworks, civil engineering, road construction, canal and pipeline construction, for laying power, fibre optic and broadband cables, in gardening and landscaping, in sports ground construction and railway track construction. For higher degrees of compaction that exceed 120 MN/m² EV2 TERRATEST® is manufacturing the Medium Weight Deflectometer which works with double force impact. In just two minutes, even inexperienced users can test, print and archive the quality of soil compaction with the handy measuring device. The Light Weight Deflectometer from TERRATEST® is equipped with voice navigation and a GPS system. The voice navigation guides the users through the measurement process via spoken commands which makes the operation of our Light Falling Weight Deflectometer child’s play in every sense of the word.
Light Falling Weight Deflectometer: Measurement ProcessThe measurement process works as follows: Place the load plate with the sensor on the ground that needs testing and connect it to the measuring computer. Now place the loading device on the load plate and switch on the electronic maeasuring computer. First, perform three initial impulses and then three measurement impulses, simply following the voice navigation announcements. This will guide even inexperienced users safely and quickly through the measurement process. The display on measuring computer shows the deflection in mm and the deflection curve after each impulse. After the third measuring impulse, the display of the measuring computer automatically shows the test result, the EVd value in meganewtons per square meter and the distance/speed ratio (s/v value). In less than two minutes, your own staff can carry out the control of compaction quality yourself on the construction site. This means you can avoid the high costs and waiting times that often arise when hiring an external testing laboratory. Often the cost of the device pays for itself within a few months.
Light Weight Deflectometer: Easy testing supported by many featuresOur Lightweight Deflectometer testing equipment enables you to print or send the test result to your PC, including the date, time and GPS data, straight from the construction site. TERRATEST 4000 STREAM also enables the user to stream the measurement results directly from the electronic measuring computer to their smartphone using the streaming USB-device. This means that with the cable model too, you have the possibility to essentially send data to the client in real time by email, directly from the construction site. The Light Weight Deflectometer is therefore even more convenient to use. The TERRATEST® “TEOLO” web based software will help you prepare a highly professional presentation of your compaction report. This consists of an individual protocol, statistical evaluation and Google®-Maps overview of all measurements carried out on the respective construction site by your Light Weight Deflectometer.
