Starlog Dataloggers

Unidata’s Starlog dataloggers are used throughout the world in an enormous variety of applications. The key features of the STARLOG range are:

  • They are robust.
  • They are easy to install.
  • They require little maintenance.
  • They are simple to use.
  • They are extremely versatile.

The Starlogger Datalogger range includes the Standard Starlogger (Model 6004D-1), the Display Starlogger (Model 6004D-2) and Prologger (7001D-1). Because of their low power consumption, they are particularly well suited to automated data collection in remote and unmanned sites. Generally dataloggers are connected to measuring instruments and sensors for data acquisition. A wide range of instruments and sensors is available from Unidata.

Starlog Dataloggers and Modules


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.
