ZFG D plus | Light Weight Deflectometer
Control the compaction test with a mobile device
With no cables restricting your movement around the device, you can easily control the measurement process via a tablet or smartphone. Compare measured values on site, create test reports and send them directly to the office. There is no need for the intermediate step of transferring the measurement data from the control electronics to an app-enabled device.
The D plus app with automatic plausibility check guides you through the test process with acoustic and/or voice control. Additional data on the client, the soil and many other details can be added immediately after the measurement. Simply use your smartphone or another mobile device for this purpose. Of course, you can also order a preconfigured tablet for the ZFG D plus. All technical details can be found in the data sheet.
