Features

The “PowerLevel” makes measurement quick, easy and accurate

The SDL30 digital level makes quick work of measuring height and distance in all types of environments—from low light to bright sunlight and artificial light. It provides unwavering accuracy in the field even in adverse environments such as tunnels, heat shimmer, and vibration. Its large internal memory, digital display, and simple operation ensure fast and accurate measurements.

Key SLD30 features include:

  • High accuracy under adverse lighting and environments
  • Four measurement modes: single-fine, repeat-fine, average and tracking
  • Water and shock resistant
  • 2000-point internal memory
  • Li-ion power system for up to 8.5 hours of continuous operation
