The Topcon RL-200 Dual Grade Rotating Laser Level is a rugged, high-performance laser system built for demanding construction and civil grading applications. Engineered for contractors who need accurate dual-axis grade control across large jobsites, the RL-200 delivers reliable self-leveling precision with an operating range of up to 800 meters in diameter — making it one of the most capable rotating lasers in its class. Whether you're cutting roads, grading pads, or directing scraper operations, the RL-200 is built to keep your crew working efficiently from the first setup to the final pass.
Product Overview & Jobsite Applications
The Topcon RL-200 is designed to handle the full range of outdoor grading and earthmoving tasks on both small residential lots and large-scale civil projects. Its dual-axis grade capability means you can set independent X and Y slopes simultaneously, eliminating the need for multiple setups or manual adjustments. The instrument features a robust, sealed housing rated for harsh site conditions, an intuitive control panel, and compatibility with Topcon's LS and LD receiver series for machine control and grade rod work. From utility trenching to parking lot construction, the RL-200 adapts to your workflow.

Key Features
- Dual-Axis Grade Control: Set independent X and Y grades simultaneously for complex slope work
- Automatic Self-Leveling: Speeds up instrument setup and reduces human error on uneven terrain
- Remote Control Ready: Compatible with Topcon remote control receivers for grade adjustments without returning to the instrument
- Variable Rotation Speeds: Choose from three speeds to optimize visibility at different working distances
- Shock-Mounted Interior: Internal components are isolated against vibration and impact common on active jobsites
- Long Battery Runtime: Up to 100 hours of continuous operation with standard D-cell batteries
- Large Leveling Screws: Oversized manual leveling screws allow fast coarse adjustment before self-leveling engages
- Out-of-Level Alarm: Audible and visual alert if the instrument is disturbed beyond its self-leveling range
Job Applications
Site Grading & Earthmoving: The RL-200's 800m operating diameter and dual-grade capability make it ideal for directing motor graders, scrapers, and dozers across large pads and road subgrades. Set your design slopes once and let your machine operators follow the receiver signal all day.
Drainage & Utility Trenching: Precise grade control is essential for positive drainage and pipe flow. The RL-200 gives trench crews a reliable grade reference for installing storm drain, sanitary sewer, and water main at consistent slopes without constant re-checking.
Parking Lot & Flatwork Layout: For commercial concrete and asphalt flatwork, the RL-200 delivers the accuracy needed to meet ADA slope requirements and drainage specs, reducing costly re-work and pour corrections.
Agricultural Land Leveling: The instrument's wide grade range and long operating radius suit irrigation field leveling and precision agricultural grading where consistent water flow across large areas is critical.

Frequently Asked Questions
- What is the maximum grade the Topcon RL-200 can set?
- The RL-200 supports dual-axis grade settings of up to ±10% on both the X and Y axes simultaneously, making it suitable for most road, drainage, and site grading applications where steep cross slopes are required.
- Does the RL-200 work with machine control systems?
- Yes. The Topcon RL-200 is compatible with Topcon's LS-series laser receivers and can be used with indicate-only machine control setups. For full automatic machine control, the receiver signal integrates with compatible grade control displays in the machine cab.
- What receivers are recommended for use with the RL-200?
- The LS-80L and LS-100D are the most commonly paired receivers for the RL-200. Both offer digital grade readout and are optimized for outdoor use. The RC-400 remote control also works with this instrument for remote grade adjustments.
- How long do batteries last in the Topcon RL-200?
- The RL-200 runs on 4 x D-cell alkaline batteries with a rated battery life of up to 100 hours under typical operating conditions. This is sufficient for multiple full workdays without changing batteries, reducing downtime on active sites.
