UNI-T LM576R Laser Levels

The UNI-T LM576R Laser Level is a professional 16-line red laser leveling instrument designed for accurate horizontal and vertical layout in construction, electrical installation, interior finishing, furniture installation, and general building work. With 360° laser emission, automatic self-leveling, diagonal-line capability, and wireless remote control, the LM576R provides continuous reference lines that help technicians establish accurate alignment without repeatedly repositioning the instrument. UNI-T specifies the LM576R as part of its LM570R/585R series of professional laser levels. 

The LM576R uses a high-brightness red SHARP laser diode with a wavelength of 635nm ±10nm and Class II laser classification. It projects 16 laser lines, providing comprehensive horizontal and vertical references around the working area. The 360° emission system is particularly useful when several surfaces need to be aligned from a single setup position, such as walls, ceilings, floors, cabinets, doors, windows, and electrical installation points.

For layout accuracy, the LM576R provides horizontal and vertical accuracy of ≤±3mm at 10m. The laser brightness can be adjusted across three levels, allowing the visible intensity to be adapted to different indoor working conditions. At the highest brightness setting, the specified visible operating radius is greater than 30m, although actual visibility depends on ambient lighting and the working environment.

The instrument incorporates an automatic leveling system based on magnetic damping and a pendulum mechanism. Its self-leveling range is ±(3±1)°, with an automatic leveling time of less than approximately 3 seconds. If the instrument is positioned outside the allowable leveling range, the laser lines flash and an audible warning is generated, helping the user identify an unstable or excessively tilted setup before relying on the projected lines.

The LM576R also includes a pendulum locking function that allows diagonal laser lines to be projected when the application requires an angled reference rather than a self-leveled horizontal or vertical line. A wireless remote control allows supported functions to be operated remotely, which is useful when the laser is positioned on a wall, bracket, or other elevated location.

Power is supplied by a 3.7V 6000mAh rechargeable lithium battery, providing more than 30 hours of operating time under the specified conditions. The instrument supports Type-C charging, and UNI-T documentation indicates that the charging interface can be used while the unit is operating. The LM576R measures approximately 135 × 87 × 150mm and is designed for operation between -10°C and +50°C.

The standard package includes the laser level, 6000mAh lithium battery, Type-C charging cable, remote control, wall-mounted bracket with metal plate, user documentation, and storage case. With its 16-line 360° projection, automatic self-leveling, adjustable brightness, diagonal mode, and long battery runtime, the UNI-T LM576R is suited to professional layout and alignment tasks where multiple reference lines are required from a single setup.
