The Kolibri Desktop offers simple and convenient software for reading and configuring data loggers locally. With 'live data', a connected device can record directly to the PC. Selected measurement data can be graphically displayed and exported.

Kolibri Cloud offers simple and convenient beta access to your measurement data with your own personal login and SSL encryption.The measurements can be displayed as graphs and the export function allows you to download your data as Excel or CSV files.

The user-friendly Datamanager software works as a central monitoring, controlling and organizing unit. It collects and displays measurements received from the ARC-1 unit and stores them in a MySQL database.
