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:
