Product Introduction
Dustproof and waterproof (IP67)
With an IP67 rating, it can withstand brief immersion in water and continue to operate normally in rainy conditions, enhancing the instrument's durability in humid or dusty environments.
Excellent shock resistance
Even after being jostled during transport, it retains its accuracy upon removal and does not require frequent calibration, thereby enhancing the stability and reliability of fieldwork.
Wide-temperature operating capability
It operates reliably within an extreme temperature range of -30°C to +50°C, making it suitable for construction sites in both the frigid north and the sweltering south.
Advantages of short viewing distances
With a minimum measurement distance of 0.5 meters (better than the 0.6 meters offered by comparable products), it can perform measurements in confined spaces such as indoor areas and utility tunnels.

Product Feature And Application
The Nanfang DSZ4A is a precise, cost-effective, and practical engineering surveying instrument. Its key strengths lie in its high operational efficiency and strong environmental adaptability, and its accuracy meets the requirements of the vast majority of standard engineering applications.
■ 32x High-Magnification
32x high-magnification + high-definition optical design Clear visibility of distant reference marks, ideal for long-distance measurements.
■ Auto-Alignment Function
Fast automatic compensation improves measurement efficiency and reduces human error.
■ Measurement accuracy
With a standard deviation of ±1.5 mm per kilometer for round-trip measurements, this is a DSZ Class 3 precision level, which is the standard in engineering surveying.
■Core Mechanism
The magnetic damping compensator is the core component, enabling the instrument to automatically compensate for minor tilts within a range of ±15′ and achieve rapid leveling.
■ Durable
It meets the IP67 rating and can be used in harsh environments, such as in the rain.It offers excellent shock resistance, allowing for direct measurement even after traveling over bumpy roads. Operating temperature range: -30°C to +50°C, suitable for all types of climatic conditions.The rotating shaft, featuring a steel shaft and steel sleeve along with a hardening process, offers enhanced wear resistance and stability.
