About us
The lightweight deflectometer is the perfect test equipment for construction companies who perform dynamic load plate test for checking the compaction quality of soil. The gauge offers a quick and easy way to perform exact measurements on site. It is used for different kinds of earthwork, civil engineering, road construction, pipeline construction, gardening and landscaping as well as for railway construction. Terratest also produces the medium sized weight deflectometer. This version of our device is perfect for working in confined spaces. Within just two minutes, even inexperienced users are able to learn how to measure, print and archive soil compaction quality data with this handy device. All TERRATEST® models are equipped with voice navigation and a GPS system. Voice navigation guides the user through the measuring process by way of easily understood announcements.
How does the dynamic load plate test work?
- Put the load plate with the sensor on the ground you want to test and connect it to the measuring computer.
- Put the drop weight on the load plate. Switch on the measuring computer by pushing the green button.
- Carry out three initial impulses first, followed by three measuring impulses. Simply follow the instructions of the voice navigation.
Experienced and unexperienced users alike are guided through the measuring menu of our Lightweight Deflectometer. After each impulse, the settlement as well as the settlement graph will be displayed in mm on the screen of the measuring computer. After the third measurement impulse, the screen of the measuring computer will display the dynamic strain model, the Evd-value in meganewtons per square meter as well as the path/speed ratio (s/v value) in mm per second.
This easy procedure delivers exact data and can be performed in only two minutes. Our equipment is thereby ideal to reduce costs for long waiting periods when relying on testing by specialized laboratories.
Results can be printed out or transferred to PC directly on site. This also includes time, date and GPS coordinates. By means of the new TERRATEST® 4000 STREAM model, data can also be streamed directly from the measuring electronics to a smartphone or tablet. With this technology even a cable-based instrument can be updated and send the required data per e-mail to your client.
TERRATEST® 2.0 software assists the user by preparing a highly professional presentation of the report – including individual log, statistical analysis and a Google® Maps overlook for all measurements carried out on the corresponding site. Using TERRATEST® 2.0 software makes documentation of tests protocols very easy and allows for a professional presentation.
At this time, more than 5000 TERRATEST Light Weight Deflectometers are being used in more than 60 countries all over the world to check compaction quality on construction sites. TERRATEST® equipment: This product stands for state of the art test equipment directly from an innovative German developer and manufacturer who guarantees you the best possible price.
