Geotechnical d-Reader

All YieldPoint geotechnical instruments can be read using the same simple unit: d-Reader. d-Reader is powered by a 9V battery (not included) and will work for several years in a usual utilization context. It is the device of choice to verify the functionality of your YieldPoint geotechnical instruments upon delivery, upon arrival at the installation site, right after installation, before and after grouting and even in the middle of a data logging session if you are in need of an instant reading for verification. Even in a sensor network using data loggers, radios and Ethernet, a d-Reader is compulsary for installation and troubleshooting.

The d-Reader is powered by a 9V battery. It automatically turns on when the user plugs in a geotechnical instrument so that it can never be left on by mistake. The blue LCD screen is backlit for excellent visibility in low light conditions. The d-Reader displays the battery level voltage and indicates when the battery must be changed.
