Topcon Rotary Lasers

Machine control, grade checking and construction lasers

Topcon's RL family of rotary lasers are a game-changer in the industry.

Featuring exceptional self-leveling capabilities, impressive battery life of up to 100 hours, and an IP-66 rating for rugged use and water resistance, Topcon rotary lasers are built to withstand the demands of the job. When it comes to choosing the perfect laser for your specific application, several factors need consideration; including range, slope types, rotation speeds, and more. Whether you require precise grading, asphalt paving, concrete paving, curb and gutter work, excavation, site surveying, underground utility mapping, field surveying, layout, or floor flatness and levelness assessments, rotary lasers are the ultimate solution.

RL-200 Series:
Optimal Grade Repeatability and Performance

Topcon’s RL-200 Series boasts a revolutionary encoding system that delivers the highest-grade repeatability of any laser, with 7 arc seconds. Its unmatched precision ensures that you’re always on grade, setup after setup, time after time. With an impressive grade range of up to 25% slope without the need for slope blocks, the RL-200 Series takes accuracy to new heights. Additionally, it offers up to 100 hours of battery life, a remarkable range of up to 1100 meters, and a fully functional remote control with the RL-200 2S model. 

 You have the choice between two models within the RL-200 Series: the RL-200 1S, designed for single slopes ranging from -5% up to +25%, and the RL-200 2S, offering dual slopes of up to ±10% in the X axis or an industry-leading -5% to +25% in the Y axis. The RC-400 remote control provides a comprehensive display of all operating information up to 300 meters away, allowing you to adjust grade, select menu settings, check operational status, and even verify battery life without physical contact with the laser. 

RL-H5A Series: Unmatched Distance, Accuracy, and Durability

The RL-H5A Series by Topcon combines exceptional distance capabilities and high accuracy, making it the go-to choice for elevation checks. With electronic self-leveling, you can simply press the power button and get to work within seconds. Even if the RL-H5A gets disturbed during the job, it automatically relevels itself, ensuring continuous accuracy. Its self-leveling motors are precise to within ±10 arc seconds, providing reliable results. 


For projects requiring elevation measurements up to 400 meters, the RL-H5A is more than capable, with a range that covers an 800-meter job site. Choose between using a rechargeable battery pack for up to 60 hours of continuous usage or rely on 4 D cell batteries for an impressive 100 hours of operation.
