Compact Level 2+/3 data logging devices

Starting out or adding capacity to validate new L2+/L3 functionality can be limited by the test vehicle space, power and budgets.

The power to do more in space constrained environments

Klas provides a range of compact and rugged vehicle data loggers that are powered by the vehicle or via the optional battery pack. Designed rugged to withstand high shock, vibrations and temperatures, the TRX range of loggers can be placed or mounted anywhere in the vehicle.

Making it the ideal solution for Level 2+/3 applications such as Driver Monitoring Systems.
