Laser rangefinders are precision instruments used to measure distances with high accuracy by emitting a laser beam and calculating the time it takes for the beam to reflect back. These devices are essential in automation, construction, surveying, and industrial applications. Key features include long-range measurement (up to several kilometers), high precision (millimeter-level accuracy), and advanced functionalities like Bluetooth connectivity, data logging, and angle compensation. Common products in this category include handheld laser distance meters, industrial-grade long-range rangefinders, and ruggedized models for harsh environments. Laser rangefinders improve efficiency in layout planning, machine alignment, and quality control processes.
