TERRATEST LWD Android App for Light Weight Deflectometer
All Light Weight Deflectometer test data directly on your android smartphone
The TERRATEST-LWD Android App transforms your Light Weight Deflectometer into a fully digital soil testing system. Designed specifically for construction professionals, geotechnical engineers, laboratories, and quality control personnel, the app allows you to operate the entire measuring process directly from your Android smartphone.
After a simple Bluetooth connection between the TERRATEST 9000 Light Weight Deflectometer and the Android device, all measurements, calculations, and reports are handled automatically within the app. There is no need for additional handheld controllers, external displays, or separate data loggers. Every test result is immediately available on your smartphone and can be reviewed, stored, and shared directly from the construction site.
Real-Time Measurement and Instant Results
During the test procedure, the TERRATEST-LWD App continuously communicates with the measuring electronics located next to the loading plate. The app records the impact force, surface deflection, and other measurement parameters in real time.
Immediately after each test sequence, the software automatically calculates important geotechnical values, including:
- Dynamic deformation modulus (Evd)
- Surface deflection values
- Soil stiffness
- Bearing capacity indicators
- Compaction quality assessments
The operator receives instant feedback on the quality of compaction, enabling immediate decisions regarding additional rolling, vibration, or earthworks activities.
Digital Construction Site Documentation
One of the major advantages of the TERRATEST Android App is the complete digital documentation of all Lightweight Deflectometer measurements.
Each test record can include:
- Date and time stamp
- GPS coordinates
- Project information
- Operator details
- Site-specific notes
- Measurement results
- Deflection curves
This digital workflow eliminates paperwork and significantly reduces administrative effort. Test results can be stored securely on the smartphone and accessed whenever required.
Share Results Directly from the Construction Site
The TERRATEST-LWD Android App allows users to send measurement reports immediately after testing. Results can be shared with project managers, consultants, laboratories, contractors, or clients directly from the jobsite.
This real-time communication accelerates decision-making and helps avoid costly delays in earthworks, road construction, pipeline installation, railway construction, landscaping, and utility projects.
Optimized for Field Use
The TERRATEST Lightweight Deflectometer includes a practical smartphone holder mounted directly on the device. This ergonomic design keeps the smartphone securely positioned while allowing the operator to focus entirely on the testing procedure.
The intuitive user interface guides even inexperienced users through the complete measurement process. Clear menus, graphical result displays, and automated calculations make compaction testing fast and reliable.
No Additional Costs
The TERRATEST LWD Android App is included as standard with every TERRATEST 9000 Light Weight Deflectometer at no extra charge. All essential functions for data collection, statistical analysis, report generation, and construction site documentation are already integrated.
For organizations that require advanced office-based reporting and project management, optional PC software is available. However, for most users, the Android App provides all necessary functions directly on the smartphone, making the Light Weight Deflectometer a truly mobile and fully digital testing solution.
The Smart Way to Perform Light Weight Deflectometer Testing
By combining advanced Bluetooth technology, automated calculations, GPS documentation, and instant report generation, the TERRATEST LWD Android App sets a new standard for modern Light Weight Deflectometer testing. The result is faster quality control, improved documentation, and more efficient construction site management—all from a single Android smartphone.
