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.
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

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)
Height Accuracy (Electronic)
1mm (With Fiberglass RAB-Code Staves)
Standard deviation for 1km double run leveling
