Benefits

Efficient: The Unilog is especially characterized by its low energy consumption as well as by its intelligent power management. The power can be supplied (depending on the infrastructure) with a 12 V battery, solar panel, or an external 230 V/ 12 V DC power supply unit.

Variable: Depending on the measurement task, up to 32 logical channels can be managed by the logger. So, for example, it is possible to connect 16 digital DS(T) 22 type SEBA-pressure / temperature probes, or three MPS-D8 multi-parameter sensors via the internal RS485 interface. Using an external A/D converter, up to 32 analog sensors can be connected.

Smart: An alarm management system in Unilog monitors all of the channels. When exceeding predefined thresholds, (for instance during a flood) the measurement intervals can be automatically shortened. Furthermore, when combined with an external modem, shorter transmission intervals (Dynamic Push) are possible. Additionally, upon request, short messages (SMS Alert) can be sent to up to eight receivers.

User-friendly: Two APPs are available for configuration and data readout of UniLog. Operating software ConfigPC (Windows) for beginners has an intuitive user interface (Wizard) for various routine tasks. SEBAConfigApp (Android) and BlueCon (our Bluetooth module) are combined to facilitate configuration and data read-out wireless with a smartphone or tablet, directly from a data logger.
