Introduction to the KRL-410 Rotary Laser

The KRL-410 Rotary Laser Level is a high-precision measuring instrument designed for professional construction, grading, and land surveying applications.
As a rotary laser level with slope functionality, it enables accurate leveling and slope adjustments (±5°), making rotary laser level with slope ideal for foundation work, concrete pouring, and drainage projects. The laser emits a 360° rotating beam with high visibility (up to 800m with a rotary laser with receiver), ensuring reliable performance even in bright outdoor conditions.

This rotary laser level kit includes a rugged carrying case, a magnetic mounting bracket, a remote control, and a rechargeable battery for extended fieldwork. The KRL-410 features self-leveling technology with an accuracy of ±1.5mm at 30m, reducing setup time and minimizing human error. Whether used for indoor alignment or large-scale outdoor projects, this rotary laser level with slope ensures efficiency and precision.

For contractors and surveyors seeking a durable and versatile tool, the KRL-410 is an excellent choice. Its robust IP66-rated housing protects against dust and water, while the rotary laser with receiver compatibility enhances long-distance measurement reliability. Upgrade your workflow with KRL-410—the ultimate rotary laser level kit for modern construction demands.

1.Superior Laser Technology
The KRL-410 rotary laser level with slope is available in two laser types: the KRL-410HVR emits a red laser at a wavelength of 635nm with an output power of 30mW, while the KRL-410HVG features a green laser at 515nm, also with 30mW output. The green laser is particularly beneficial for outdoor use, providing enhanced visibility in bright conditions, making the KRL-410 an ideal rotary laser level for grading.

2.Precision Leveling
This rotary laser level employs electronic leveling technology, utilizing one gyroscope and dual-axis electronic sensors to ensure exceptional accuracy. With a leveling range of ±5° and a precision of ±0.5mm over 10 meters, the KRL-410 guarantees reliable performance for all leveling tasks. Whether you are setting foundations or grading land, this tool ensures you achieve the perfect level every time.

3.Impressive Working Diameter
The KRL-410 Rotary Laser boasts an extensive working diameter. When used with the LP500 receiver, it can reach distances of over 1000 meters, and with the LP700, it supports distances of up to 800 meters. This capability is essential for large-scale projects, allowing for efficient and effective leveling over significant areas.

4.Versatile Rotation and Scan Settings
Designed for adaptability, the KRL-410 rotary laser level with slope features adjustable laser rotation speeds of 0, 300, 600, 1000, and 1500 RPM, powered by a permanent magnet brushless hollow motor. Additionally, the area scan functions—15°, 45°, 90°, and 180°—allow users to customize the laser beam’s coverage based on their specific needs, enhancing its functionality as a rotary laser level for grading.

5.User-friendly Operation
The KRL-410 Rotary Laser is equipped with a remote control (RC100) for slope operations, enabling users to manage settings from a distance of up to 150 meters. The main unit features a straightforward interface with 12 keys and 5 indicator lights, ensuring seamless operation. Users can also calibrate the device via remote control or a dedicated app, adding to its convenience.

6.Durability and Long Battery Life
Built to withstand challenging job site conditions, the KRL-410 has an IP65 protection grade against dust and water. The lithium battery provides an impressive working time of 15-20 hours, with options for extended battery life. This ensures that the rotary laser level remains operational throughout lengthy projects.
