Precision Digital Leveling with Trimble DiNi03

The DiNi03 is designed for projects where reliable elevation data is more important than simply obtaining a quick level reading. Its electronic measurement system works with a bar-code staff to automate staff reading and reduce dependence on manual observation. The instrument also supports multiple leveling procedures and line-adjustment workflows, making it useful for precision control networks, deformation monitoring and engineering projects where consistent height measurements are required.
