B.R.A.IN.
Read full descriptionHide full description
B.R.A.IN (Borehole Readout Array for Inclinometers) is the application for managing SISGEO MEMS inclinometer systems, digital spiral meters and digital T-REX incremental extensometers. With B.R.A.IN app you will always have under control all the main parameters of the measuring system (i.e. probe and reel electronics’ temperature and humidity). By activating the "alarms" the app will propose you alert messages (i.e. probe calibration expired). New sites and boreholes’ set up is intuitive and permits to add descriptions and additional information useful for data processing (i.e. save latitude and longitude of borehole head using the integrated GPS of your device). During the reading procedure, the app informs you if the reading is stable or not, at which depth is the probe and the checksum value using the conjugated reading (180° reverse reading). The data and graphs of the survey could be immediately displayed, saved on the device memory or cloud, or shared i.e. by email. B.R.A.IN app is the best complement for KLION, the software developed by SISGEO for data analysis and for creating reports.
