Product Introduction
Superb optical system
The DSZ3 is equipped with a 32x upright binocular telescope that delivers clear, lifelike images. Combined with a 40mm large-aperture objective lens, it provides a bright, sharp field of view in any lighting conditions.
Automatic Leveling Compensator
The DSZ3 features a magnetic damping compensator that automatically restores the line of sight to a horizontal position via magnetic damping when the instrument is slightly tilted, ensuring measurement accuracy and stability.
Expansion Joint Inspection Button
Before taking a measurement, simply press this button to quickly check whether the compensator is functioning properly, ensuring the reliability of every measurement.
Exceptional adaptability to the environment
■ Waterproof and dustproof: The IP67 rating means it is not only dustproof but can also be removed from water after brief immersion and continue to function, which is a major advantage in rainy or foggy weather or on damp construction sites.
■ Temperature and shock resistance: The instrument has undergone rigorous testing in harsh environments, including extreme temperatures and vibration, and its rugged construction makes it suitable for use on rough terrain.

Product Feature And Application
The Nanfang DSZ3 level is a reliable, highly adaptable, and cost-effective entry-level professional surveying instrument. While it lacks the high-end features of top-tier precision levels, it meets the needs of the vast majority of third- and fourth-order leveling surveys and construction projects, making it a reliable and user-friendly choice.The key advantage of this instrument is that it simplifies the complex process of establishing a horizontal line of sight, transforming the measurement process from the previous "fully manual fine-tuning" to the current "one-button automatic" operation. The operator need only perform a rough leveling; the instrument's internal magnetic damping compensator then automatically adjusts the line of sight to a horizontal position using the principle of gravity, significantly improving measurement efficiency and eliminating human error.
Thanks to its reliable performance and excellent environmental adaptability, the Nanfang DSZ3 is capable of handling a wide range of measurement tasks:
Applications of National-Level Surveying
Primarily used for national third- and fourth-order leveling surveys.When used in conjunction with a micrometer, accuracy can be further improved, enabling second-order leveling surveys and precise settlement monitoring.
Applications in the Construction Industry
Whether for elevation control in construction projects or elevation surveys for roads and bridges, it is the ideal tool.It is also widely used in fields such as water resources management, hydrology, and agricultural water resource surveying.
Applications in Precision Engineering and Monitoring
Can be used for leveling during the installation of large machinery and equipment.Can be used for monitoring deformation and settlement in buildings, excavation pits, and other structures.
