It’s becoming increasingly important to ensure that products are free of defects and are delivered strictly on time.

Needless to say, you want your products to be delivered in mint condition. So it’s all the more important to keep a watchful eye on them after they leave the factory.

This intelligent tracker reliably detects all shipping and storing irregularities.

The g-log data logger records accelerations, impacts and vibrations. The timeline of each acceleration event is recorded in all three axes (length, width and height). Temperature and humidity can also be logged using an external combination sensor.

This makes the g-Log Data Logger an ideal instrument for seamless monitoring of the shipping process, since with one device you can log both mechanical stresses and environmental factors.


  • Shock measurement in all three axes
  • Detailed Shock timeline with time stamps
  • Temperature and humidity logging via external detectors
  • Dew point calculation
  • 24 month battery life
  • Tamperproof - password protected
  • Sturdy aluminum housing; easy to mount
  • Analyses are extremely simple to realize using the device software
  • Generous data storage capacity

Outstanding reliability

All data are stored in the g-log data logger’s non-volatile memory, which means that the data remain in the memory even if the battery goes dead. All programming actions are password protected and all changes are logged, thus rendering measurement readings tamperproof and allowing for immediate detection of any manipulation attempt.

Sturdy housing
Our g-Log data loggers were developed specially for use under severe conditions. The device’s measurement electronics are protected by a sturdy, watertight aluminum housing (IP 65).
