UNI-T LM575R Laser Levels

The UNI-T LM575R Laser Level is a professional 12-line red laser leveling instrument designed for accurate horizontal and vertical alignment in construction, electrical installation, interior finishing, furniture installation, and general layout work. Its high-brightness red laser projects reference lines around the working area, making it easier to establish accurate alignment points and continuous leveling references during installation and construction tasks.

The LM575R uses a SHARP red laser diode with a wavelength of 635nm ±10nm and Class II laser classification. It produces 12 laser lines with a 360° emission angle, allowing the user to establish horizontal and vertical reference lines without repeatedly repositioning the instrument. This configuration is particularly useful when working on walls, ceilings, floors, cabinets, doors, windows, and other structures that require accurate alignment. 

The laser level provides horizontal and vertical accuracy of ≤±3mm at 10m, making it suitable for professional layout applications where controlled alignment is required. Its laser brightness can be adjusted through three levels, allowing the visible line intensity to be adapted to different indoor working conditions. At maximum brightness, UNI-T specifies an operating radius of more than 30m, although visibility in practical conditions depends on ambient lighting and the working environment. 

A built-in automatic self-leveling system uses magnetic damping and a pendulum mechanism. The self-leveling range is ±(3±1)°. When the instrument is positioned outside its leveling range, the laser lines can flash and the unit can provide an audible warning, helping prevent inaccurate layout caused by an excessively tilted setup. The pendulum can also be locked for manual and diagonal-line applications. 

The LM575R also supports diagonal laser mode, which is useful when an installation requires lines at angles rather than strictly horizontal or vertical references. A wireless remote control allows the user to operate supported functions without needing to approach the instrument after it has been positioned. This can be convenient when the laser is mounted on a wall, bracket, or other elevated location. 

Power is provided by a 3.7V 6000mAh rechargeable lithium battery, with a specified operating time of more than 30 hours. Charging is performed through USB Type-C. The instrument has a compact 135 × 87 × 130mm housing and operates within a temperature range of -10°C to 50°C. The package includes the laser level, rechargeable battery, remote control, wall-mounted bracket with metal plate, Type-C charging cable, user manual, and storage case. 

With its 12-line 360° projection, automatic self-leveling, adjustable brightness, diagonal mode, remote control, and long battery runtime, the UNI-T LM575R provides a practical reference system for precise layout and alignment across a wide range of construction and installation tasks.
