Compact Self‑Leveling Cross‑Line Green Laser – UNI-T LM570LD-II

The UNI-T LM570LD-II represents the pinnacle of compact laser leveling technology, designed to provide high-accuracy vertical and horizontal references without the bulk of traditional levelers. This 2-line green laser leveler is an essential tool for project layout, allowing professionals to achieve perfect cross-line projection for everything from home renovation to complex industrial building construction. Its high-intensity green diode laser is specifically chosen for its ability to remain visible in bright workplaces where standard red lasers often fail.

Rapid Self-Leveling & Intelligent Damping

Equipped with a precision gravity-pendulum damping system, the LM570LD-II automatically finds true level within a ±3∘ range. The stabilization process is exceptionally fast, achieving a solid reference line in just 3 seconds, which maximizes productivity on busy worksites. For specialized tasks, the unit also features a Manual Mode, which locks the pendulum and allows the user to project fixed lines at any angle—ideal for installing staircases, sloped handrails, or decorative patterns.

High-Visibility Green Laser Diode

Utilizing a 520nm wavelength green laser diode, the LM570LD-II provides lines that are significantly sharper and easier for the human eye to track than red alternatives. This visibility is crucial for high-precision tasks like wall and floor tile alignment, where even a slight deviation can ruin the final finish. The device maintains an accuracy of $\pm 3\text{mm}$ at a 10-meter distance, ensuring professional-grade results for every measurement.

Ergonomic Design & Job-Site Durability

The LM570LD-II is built to withstand the rigors of an active construction environment. Its compact housing (85.5mm x 62mm x 90.3mm) and lightweight 240g frame make it highly portable, fitting easily into a tool belt or pocket. The unit is powered by two 1.5V AA (LR6) batteries, offering up to 4 hours of continuous operation with all lasers active. For added versatility, it features a 1/4-inch tripod mount, allowing for stable positioning on various surfaces or mounting brackets.

Maintenance and Best Practices

To ensure the accuracy and longevity of your UNI-T LM570LD-II, follow these professional maintenance steps:

• Accuracy Verification: It is recommended to perform an accuracy test before the first-time use and regularly thereafter, especially for high-precision jobs.

• Pendulum Protection: Always ensure the pendulum is locked by turning the meter off when not in use or during transport.

• Battery Care: Remove batteries if the meter will not be used for a long period to prevent leakage damage.

• Environmental Storage: Clean the outer plastic parts with a damp cloth; avoid harsh solvents that could damage the casing.
