The MSR 165 can be supplied with an interface for plugging in a standard SD card (one 4GB microSD card is included). Please note that this expansion slot with plugged-in microSD card only meets the protection category IP60.

PC Software

The integrated software in each unit includes Free Setup, Reader, Viewer and Online software (Windows 98/ME/2000/XP/Vista/7) to record and evaluate data. All measurement parameters can be rapidly transferred to a PC via the USB connection both during the measurement operation and once the measurement task has been completed. Each unit includes an integrated clock (RTC), allowing data from as many MSR 165 units as required to be synchronised and merged into a single data record.
