FOIF DSZ1 Precision Automatic Level

The FOIF DSZ1 is a precision automatic level designed for applications where reliable elevation measurement and improved leveling accuracy are important. As an upgraded model based on the well-known DSZ2 series, it combines a higher-performance optical system with an automatic compensator and a built-in horizontal circle. The DSZ1 is suitable for professional leveling, construction engineering, deformation monitoring, mine surveying and precision installation work.

Key Features

• Precision leveling performance for demanding surveying work

• 38× telescope with a 50mm objective aperture

• Up to ±0.7mm standard deviation for a 1km double run when used with an indium steel millimeter staff

• Automatic compensator with ±15′ working range

• Built-in horizontal circle for convenient angle reference

• IP55 protection for improved field durability

• Designed for professional surveying and precision engineering applications

Precision Leveling for Professional Applications

The DSZ1 is a practical choice when standard automatic levels are not enough and higher leveling accuracy is required. Its optical system and compensator are designed to support consistent field measurements, while the built-in circle and improved housing make routine operation more convenient. It can be used for second- and third-order leveling, settlement and deformation monitoring, construction measurement, mine surveying and industrial equipment installation.
