  • 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.
  • Use in conjunction with the Digital Level Rod
  • Warranty: 2 Years 
  • Supplied with BDC46B Li-ion battery, CDC68 115VAC Charger, dust cover, tool kit, operators manual, carrying case.
  • (Former Part#'s 73830 and 210115034)
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
Make measurements quick, easy, and accurate: 
  • The SDL30 is an accurate, dependable digital level that combines user-friendly convenience with maximum functionality. 
  • All you have to do is aim the staff, adjust the focus, and then with a single touch of a key the SDL30 accurately measures height and distance. 
  • The results are easy to see on the LCD display. 
  • High-speed measurement 
  • Consistent performance 
  • Water and shock resistant 
  • 2000-point internal memory 
  • Li-ion power system for up
Fast Measurements:
  • Aim, focus and press a key. 
  • Height and distance are simultaneously measured in 2.5 seconds, 20 percent faster than ordinary digital levels.
Reliability you can count on:
  • You get superior measurement capability under all conditions. 
  • Even when the staff surface is partially shaded, or in dim light where the brightness at staff surface is as low as 20 lux*, the SDL30 consistently provides accurate measurements without downtime. 
  • * 20 lux is defined as the minimum brightness with which human face can be recognized.
Automatic recognition of inverted staff: 
  • The SDL30 automatically recognizes directions of RAB-Code staffs and displays the results with a minus sign (-) when the staff is inverted. 
  • Height of ceiling, overpasses, bridges,road signs, tree branches, tunnel crowns, and other objects can be easily measured without a calculator.
Wave-and-Read technology: 
  • The innovative “Wave-and-Read” technology provides an additional survey style. 
  • The SDL30 tracks the RAB-Code staff waved back and forth to read the correct height. 
  • The staff reading becomes the minimum when it is in vertical position. 
  • The SDL30 automatically detects the least value of staff readings.
Choose your accuracy: 
  • SDL30: 0.4 mm (Super-Invar Staff) / 0.6 mm (Invar) / 1.0 mm (Fiberglass) - This Unit
  • SDL50: 0.6 mm (Super-Invar Staff) / 0.8 mm(Invar) / 1.5 mm (Fiberglass) - Available here.
  • Choose the digital level and staffs according to the accuracy* you need. 
  • Sokkia offers the top of-the-line SDL1X model for higher accuracy of up to 0.2 mm. - Available here
  • * 1 km double-run leveling
Robust internal memory:
  • Up to 2,000 measurements of elevation or height differences can be recorded in the internal memory. 
  • Auto mode records data as soon as the measurement is taken, while manual mode allows you to check the measurement results before recording. 
  • Stored data is easily exported using the “Spectrum Link” software.
Convenient on-board Programs:
  • The on-board measurement programs of SDL30 facilitate leveling and setting-out tasks. 
  • Programs include: 
    • Elevation 
    • Height Difference 
    • Cut and Fill Setting-out 
    • Setting-out in Distance
Elevation/Height difference:
  • The SDL30 calculates height difference between backsight (BS) and foresight (FS) 
  • Elevation of foresight can be calculated by inputting BS elevation
Cut and Fill Setting-out: 
  • Slope can be set using Cut and Fill Setting-out program 
  • Leveling is possible by inputting the height difference zero (0)
