UNI-T LM555LD Laser Leveler
The UNI-T LM555LD Laser Leveler is a reliable and versatile cross-line leveling tool designed for precision alignment of horizontal and vertical planes and their intersection (V-H cross point). It projects one horizontal line and four vertical lines (4V1H), making it ideal for accurate layout tasks in construction, cabinetry, flooring, and renovation work.
Built for durability and field use, the LM555LD features an IP54-rated housing that resists dust and water ingress. It self-levels via a gravity-pendulum mechanism with magnetic damping within a ±3.5° tilt range, reaching stabilization in under 3 seconds. The green laser ensures visibility, and its accurate beam projection (±2 mm at 10 m) supports precise alignment.
Portability and convenience come together with a built-in 3.7 V, 4000 mAh rechargeable Li-ion battery that powers the unit for over 5 hours with all lasers active. Compact and light around 1 kg and sized ~126 × 120 × 205 mm it comes with safety goggles, USB cable, adapter, mark ruler, and an English manual.
