Read full description

TERRATEST APP for Light Weight Deflectometers offers maximum comfort for control of light weight deflectometer TERRATEST® 5000 BLU. No personal intervention is required; remote control and data transfer is initiated from smartphone or tablet via Bluetooth®. The process is furthermore simplified by Magic Eye and voice navigation. The WiFi dongle available upon request is used to load measurement data incl. curves, GPS coordinates and a Google Earth® satellite photo of the site, directly from the instrument electronics to the smartphone. Physical connection of measurement electronics is no more required. Another benefit is the possibility of completing the entire documentation procedure before leaving the construction site: Establish logs with EvD value, date and time, settlement curves, coordinates and satellite photo, and send the .pdf file to the office or to the client without delay. A photo captured by the camera of the smartphone itself can be added as well. The feature of data handling by means of this APP can also be used for TERRATEST 5000BLU/TERRATEST 4000 STREAM/4000 USB models.
