SOUTH DL-2003A Digital Level

The SOUTH DL-2003A is a high-accuracy digital level designed for precision elevation measurement, engineering surveying and settlement monitoring. It combines electronic staff reading with an onboard graphical interface, allowing common leveling tasks to be completed directly in the field. Its data management and post-processing workflow also makes it suitable for projects requiring organized leveling records and adjustment analysis.

Key Features

• 0.3 mm/km leveling accuracy with an Invar staff

• 3.0-inch color LCD touchscreen

• Graphic onboard interface for simplified field operation

• Built-in leveling, stakeout and line measurement functions

• Support for multiple leveling procedures and field checks

• Bluetooth and RS-232 communication

• USB storage support for convenient data transfer

• 128 MB internal storage

• Magnetic-damped compensator

• IP65 protection for demanding outdoor work

• Up to 16 hours of operating time

Precision Leveling and Settlement Monitoring

The DL-2003A is particularly suited to projects where precise elevation control and organized field data are both important. Its onboard software supports common leveling procedures and can assist with tasks such as height measurement, stakeout and line measurement. Data can be transferred for further processing, while the associated SOUTH post-processing workflow supports adjustment and analysis of leveling networks.

This makes the DL-2003A a practical choice for precision control surveys, settlement observation and engineering projects that require repeatable elevation measurements rather than simple routine leveling.
