The Topcon RL-200 2S is a professional-grade dual slope rotating laser engineered for contractors who need precise, repeatable grade control on complex earthwork, concrete, and drainage jobs. This complete kit—model 314920762-1T—pairs the RL-200 2S laser head with the LS-80X digital receiver, a tenths rod, and a heavy-duty adjustable tripod, giving your crew everything required to hit grade accurately from day one on the jobsite.
Dual-Axis Slope Control for Complex Grade Work
Unlike single-slope lasers, the RL-200 2S lets you simultaneously set independent X and Y axis slopes across its full ±10% grade range. Whether you're establishing two-way drainage planes on a parking lot, matching a building pad to an architect's drainage spec, or grading a concrete slab to a defined fall, the RL-200 2S handles it in a single setup without manual tilt compensation. The instrument self-levels within ±4° and locks in your slope values with push-button simplicity, reducing setup time and eliminating manual grade calculations in the field.

Jobsite Applications
Concrete Flatwork & Slab Pours: Set dual-pitch grades across large commercial slabs and warehouse floors. The RL-200 2S holds your slope reference throughout the pour so finishers can screed to exact spec without re-checking with a level.
Site Grading & Excavation: Use the wide 800m operating diameter to control cut-and-fill operations across large sites. Operators can read grade directly from the LS-80X mounted on the blade, improving pass efficiency and reducing survey interruptions.
Parking Lot Drainage: Establish two-direction cross slopes that meet ADA and engineering drainage requirements. Independent X/Y slope adjustment means you can dial in a 1.5% cross slope and 0.5% longitudinal fall simultaneously without repositioning the instrument.
Underground & Pipe Work: Set consistent invert grades for storm drain, sanitary sewer, and utility trenches using the tenths rod and LS-80X for sub-inch accuracy along the run.

Frequently Asked Questions
- Can the Topcon RL-200 2S set slope on both axes at the same time?
- Yes. The RL-200 2S supports simultaneous dual-axis slope up to ±10% on both X and Y, making it ideal for two-way drainage planes and complex grade applications without secondary instrument setups.
- What is the working range of this laser kit?
- With the included LS-80X receiver, the RL-200 2S operates over a diameter of up to 800 meters, suitable for large commercial grading, site development, and machine control applications.
- How long does the battery last on a single charge?
- The rechargeable lithium-ion battery delivers up to 40 hours of continuous runtime, enough to power through multiple full workdays before needing a charge.
- Is the Topcon RL-200 2S waterproof enough for outdoor use in rain?
- Yes. The RL-200 2S carries an IP66 rating, meaning it is fully protected against dust ingress and powerful water jets, making it suitable for year-round outdoor contractor use in wet or dusty conditions.
