The 12 line laser level has multiple practical functions, making it perform well in various measurement scenarios. Firstly, it offers two charging modes, where users can choose to use lithium batteries for power supply or connect directly via USB for high flexibility. In addition, the instrument is equipped with Bluetooth function, which supports connecting to an APP or using a remote control for remote control, greatly improving the convenience and flexibility of operation. For outdoor measurement needs, it is specially designed with a pulse mode that can be used in conjunction with a laser receiver to ensure accurate measurements can still be taken in outdoor environments. The design of the instrument also takes into account different measurement requirements, and users can switch between vertical and horizontal lines separately as needed to avoid unnecessary errors. At the same time, the 12 line laser level has self leveling and manual leveling functions, ensuring accurate measurement results in complex terrain or flat environments. These powerful and diverse features make the laser level an ideal tool for various application scenarios such as construction, decoration, and outdoor measurement.
