Starlog Dataloggers

Dataloggers Overview

  • Overview

    The Starlogger range includes the Standard Starlogger (Model 6004D-1), the Display Starlogger (Model 6004D-2) and the top-of-the-line Prologger (7001D-1).

    Because of their low power consumption, they are particularly well suited to automated data collection in remote and unmanned sites.

    Unidata data loggers are connected to measuring instruments and sensors for data acquisition. A wide range of instruments and sensors is available from Unidata.

    The acquired data can be obtained from the data loggers by connecting a computer directly to the unit or by using a remote telemetry system, or the analogue, GSM and NextG/3G communications networks.

    Configuration Considerations
    To choose the model of the data logger best suited to your data logging project, consider both the duration of the project and the type of measurement instrument that will be used. The table below provides an overview of the features offered by each data logger. Microloggers are only available for OEM and high volume users.

    Note that a number of Unidata’s instruments incorporate a Micrologger. Standard features of the Micrologger are also listed in the table opposite for comparison.
