Sokkia SDL 30 Digital Level

Sokkia proudly presents the POWERLEVEL SDL30, a digital level that has been further improved by adding a large internal memory. All you have to do to measure height and distance is aim the unique RAB-Code staff, adjust the focus and press a single key. The results are immediately indicated digitally on the LCD display and can be recorded in the internal memory - making the SDL30 the ideal instrument for quick and easy leveling.

"Digital" Makes Measurement Quick and Easy

"How can we make leveling work quicker and easier?" was the question foremost in the minds of the SDL30 designers. Sokkia boldly eliminated the complex functions that complicate operation, resulting in an extremely simple and efficient digital level designed primarily for height and distance measurement - the essential role of the "Level". Measurements are made within three seconds with a single touch of a key, and can be stored immediately in the internal memory.

Suited To Various Environments

The SDL30 can be used in a wide variety of differing environments. It can be used in low light conditions as long a the cross hair is visible, as well as in very bright direct sunshine. Artificial lighting presents no problems, so you can survey indoors or in tunnels. Even in the dark measurement can be carried out using a small flashlight. The SDL30 has been designed to provide stable accuracy under these conditions and in adverse operating environments such as uneven light and shade, heat shimmer, and vibration.

Advanced Power System

The SDL30 is powered by a new Lithium-ion-battery which is capable of supplying power continuously for seven hours. Long battery life is assured even with frequent recharging.

Four Measurement Modes

Four measurement modes are available: Single-Fine, Repeat-Fine, Average and Tracking.

Water and Shock Resistant Structure

The SDL30 boast water-resistance unmatched by other digital levels. Complying with IPX4 (IEC60529), the SDL30 is protected from water splash from any direction. Sokkia's proven shock-resistant pendulum compensator with magnetic damping system ensures accuracy and durability.

Data Storage

To further enhance the leveling work, an internal memory with a recording capacity of up to 2000 points of data has been added to the SDL30. This also enables you to create up to 20 JOB files. Either automatically or by using the keys on the instrument, you can define point numbers and select attributes of recorded data and check them while doing or after finishing the job.
