• Easy, accurate measurement for construction and general applications. 
• Sokkia brings the benefits of digital leveling to construction applications at an affordable price with the reliable, easy-to-use SDL50 Digital Level. 
• In less than 3 seconds and with the touch of a key, height difference and distance can be measured and the result is stored in internal memory. 
• The SDL50 minimizes human error and maximizes the ease of leveling work, allowing increased productivity and performance. 
• Supplied with BDC46B Li-ion battery, CDC68 115VAC Charger, dust cover, tool kit, operators manual, carrying case. 
• Use in conjunction with the Digital Level Rod
• Warranty: 2 Years
• (Former Part#'s 738050, 210115037)

Key SDL50 features include: 

• Adjusts height and distance simultaneously 
• Measurement is less than 3 seconds (single & repeat modes) 
• Water 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 SDL50 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 SDL50 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 SDL50 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 SDL50 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 SDL50 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 SDL50 automatically detects the least value of staff readings.

Choose your accuracy:

• SDL50: 0.6 mm (Super-Invar Staff) / 0.8 mm (Invar) / 1.5 mm (Fiberglass) - This Unit
• SDL30: 0.4 mm (Super-Invar Staff) / 0.6 mm (Invar) / 1.0 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 SDL50 facilitate leveling and setting-out tasks.
• Programs include:
  • Elevation
  • Height Difference
  • Cut and Fill Setting-out
  • Setting-out in Distance

Elevation/Height difference:

• The SDL50 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)
