Product Introduction
Core Optical and Ranging System
The NL132 features a right-image telescope system, which means that the image seen through the eyepiece is upright and stereoscopic. Compared to older inverted telescope systems, this better aligns with human visual habits, effectively reducing eye strain during prolonged use and minimizing reading errors.
Accuracy and Compensator Systems
As the core component of the measuring instrument, the NL132 compensator determines its accuracy and stability.
Mechanical Design and Manufacturing
The mechanical structure and design of this product focus on technical details and performance parameters in three key areas: the turret system, material processing, and the focusing mechanism.
Environmental Adaptability and Physical Parameters
This highlights the product's design features regarding environmental adaptability and physical specifications, including operating temperature range, protection rating, total weight, and dimensions, emphasizing its stability and portability in various environments.
Summary of Use Cases
The Nanfang NL132 level is a cost-effective engineering-grade surveying instrument. It fills the market gap between high-precision optical levels (such as the NL232 series) and standard levels. While ensuring an accuracy of ±2.5 mm, its short sighting distance of 0.4 meters makes it particularly suitable for users who require high precision but have limited budgets; it is also ideal for use in environments with limited space, such as interior renovation projects or small-scale earthwork projects.

Accuracy and Compensator Systems
■ Measurement accuracy
The standard deviation for a 1-kilometer round-trip measurement (i.e., the 1-kilometer round-trip error) is ±2.5 mm. This meets the specifications for national third-order leveling surveys and is suitable for construction surveying in most industrial and civil engineering projects.
■ Expansion joint type
Air-damped expansion joint.
■ Automatic Leveling
As long as the bubble remains within ±8' of the black circle, the level will automatically self-level.
