KRL-405 Rotary Laser – Precision Multi-Functional Measuring Instrument

The KRL-405 Rotary Laser is a high-performance multi-functional rotary laser designed for construction, surveying, and industrial applications. With both rotary laser green beam and rotary laser red beam options, this versatile tool ensures optimal visibility in various lighting conditions, making it ideal for indoor and outdoor use.

As a multi-functional rotary laser, the KRL-405 offers automatic self-leveling, manual slope mode, and a 360° rotating beam for full jobsite coverage. The rotary laser green beam (520nm) provides up to 4x better visibility than traditional red beams, perfect for bright environments, while the rotary laser red beam (635nm) remains a reliable choice for standard applications. With a working range of up to 800m (with detector) and ±1.5mm accuracy at 30m, this laser ensures professional-grade precision.

KRL-405 multi-functional rotary laser include:

Switch between rotary laser green beam and rotary laser red beam as needed
Dustproof and water-resistant for tough job sites
Enhances efficiency in large-scale projects

Whether you need high-visibility alignment or long-range leveling, the KRL-405 multi-functional rotary laser delivers unmatched performance.

1.High-Visibility Laser for Maximum Clarity

The KRL-405HVR model features a Rotary Laser green beam-red laser (635nm, 30mw), while the KRL-405HVG offers a brighter Rotary Laser red beam-green laser (515nm, 30mw), providing enhanced visibility in bright sunlight and over extended distances.

With a working diameter of up to 1000m (using LP500 receiver), this Rotary Laser is perfect for large-scale construction and outdoor applications.

2.Advanced Electronic Leveling for Ultimate Precision

KRL-405 Rotary Laser Equipped with 1 gyroscope + 1 dual-axis electronic sensor, the KRL-405 ensures fast and accurate self-leveling within ±5°, with an exceptional leveling accuracy of ±0.5mm/10m.

The Rotary Laser also supports manual slope adjustment (±10%), allowing for precise grading and sloped surface work via the included RC100 remote control.

3.Adjustable Rotation Speed & Scanning Modes

The permanent magnet brushless hollow motor enables variable rotation speeds (0/300/600/1000/1500 RPM), optimizing visibility and battery efficiency.

Multiple area scan modes (15°/45°/90°/180°) provide flexibility for different job requirements, from detailed interior work to wide-area outdoor leveling.

4.Long Battery Life & Rugged Durability

Powered by a replaceable lithium battery, the KRL-405 offers 15-20 hours of continuous operation, with optional extended batteries available for longer shifts.

Built to withstand harsh conditions, KRL-405 Rotary Laser boasts an IP65 protection rating and operates in temperatures ranging from -20℃ to +50℃, ensuring reliability in extreme environments.
