Operating software (Windows) for programming, calibration and data read-out of SEBA loggers and for the calibration of SEBA-pressure and multi-parameter sensors. With SEBAConfig, all routine tasks for maintaining the measuring operation are settled with SEBA loggers and sensors. In addition to configuration, calibration and data reading, a remote access to online stations via GPRS or modem is also possible. Read-out time series are also displayed by DEMASvis graphically and in hydrograph form.
