Equipped with a 4V1H1D laser beam, the device provides excellent coverage for horizontal and vertical leveling tasks.  The ±2mm/7m leveling accuracy guarantees precise measurements to ensure your projects are perfectly aligned. With a self-leveling range of ±3°, this laser level can be relied upon to quickly and accurately level any surface. The working wavelength of ZCLY002 laser level gauge is 520nm, providing a clearly visible laser beam. This enhances visibility, making it suitable for both indoor and outdoor use. The horizontal laser angle is 120°, the vertical laser angle is 150°, and the coverage is wide, allowing you to complete tasks efficiently. The working range of this laser level is 0-20m, which can meet various distance and project requirements.
