Non-volatile, industry standard Flash technology ensures that your valuable data cannot be accidentally erased, disrupted, or altered. Recommended over commercially available memory cards, NRG’s SD cards are industrial-rated for operation across the data logger’s full temperature range.

Use our 512 MB SD card when using the SymphoniePRO data logger in typical wind and solar resource applications and when 1 Hz sample data storage is not planned. Use our larger 2 GB SD card if 1 Hz sample data storage is required.
