Built for Two-Axis Grade Control on Demanding Job Sites

The Topcon RL-200 2S is a professional-grade dual slope rotating laser designed for contractors who need simultaneous cross-slope control in two perpendicular axes. Whether you're grading a parking lot with compound drainage slopes, preparing a sports field with precise crown grades, or setting up a building pad with multi-directional fall, the RL-200 2S delivers the accuracy and reliability that production grading demands. Express Tools is an authorized Topcon dealer offering multiple RL-200 2S package configurations to match your workflow and budget.

System Overview & Job Site Applications

The RL-200 2S builds on Topcon's proven rotary laser platform by adding full dual-axis electronic slope capability—both the X and Y axes can be independently set to grade, eliminating the need to manually tilt or shim the instrument on complex layouts. The system features Topcon's automatic self-leveling within its operating range and pairs with the LS-80X laser receiver for extended range detection. Powered by standard alkaline D-cell batteries, the RL-200 2S avoids proprietary battery costs while delivering full-shift runtime in the field. Remote control operation via the included RC-200 remote lets operators adjust grade settings from the machine cab without returning to the instrument—a critical time-saver on dozer and grader applications.

Job Site Applications

Parking Lot & Lot Grading: Set compound drainage slopes in a single instrument setup. The RL-200 2S holds both cross-slope and longitudinal grade simultaneously, keeping water moving toward drains without constant instrument adjustments across large paving and grading areas.

Sports Field Construction: Athletic field grading requires precise crown grades and end-to-end fall control. The 2S model lets crews match spec sheets that call for different slopes in both directions, reducing re-grading passes and improving finished surface quality.

Building Pad Preparation: Multi-directional drainage requirements on commercial building pads are easily managed with dual-axis capability. Set slab drainage fall in both directions simultaneously while maintaining a consistent reference plane for footing and foundation crews.

Road & Ditch Work: Set cross-fall on road subgrades or drainage ditch profiles. The wide slope range and long operating diameter make the RL-200 2S suitable for highway subgrade work, subdivision street grading, and utility corridor preparation.

Frequently Asked Questions

What is the difference between the Topcon RL-200 1S and the RL-200 2S?

The RL-200 1S provides single-axis slope control, allowing you to set a grade in one direction while the other axis remains level. The RL-200 2S adds full dual-axis capability, letting you independently set slope in both the X and Y axes at the same time—essential for compound grade applications like parking lot drainage, sports field crowns, and building pads that slope in two directions.

Does the Topcon RL-200 2S include a receiver?

Package configurations vary. Express Tools offers the RL-200 2S both as an instrument-only option and in complete kits that include the Topcon LS-80X laser receiver and RC-200 remote control. Review the available package options on this page or contact our team to confirm what's included in each configuration before ordering.

What batteries does the RL-200 2S use and how long do they last?

The RL-200 2S runs on standard D-cell alkaline batteries, which are widely available at hardware and convenience stores. Topcon rates the battery life at approximately 100 hours of continuous operation under normal conditions, making it practical for multi-day use without frequent battery changes—no proprietary battery packs required.

Can the Topcon RL-200 2S be used with machine control systems?

The RL-200 2S is compatible with Topcon's grade control accessories including the RD-200 in-cab readout and RC-200 remote, making it suitable for dozer and motor grader cab-controlled grading setups. For full 3D machine control integration, a dedicated machine control system would be required, but for slope-based blade control applications the RL-200 2S with grade indicators is a proven and cost-effective solution.
