Topcon RL-200 2S Dual Slope Grade Laser Package, w/ LS-100D Receiver (314920782-2ET) Rechargeable Batteries, Inches Rod and HD Elevator Tripod

The Topcon RL-200 2S is a professional-grade dual slope rotating laser designed for contractors who need precise two-axis grade control on demanding jobsites. This complete package includes everything you need to start grading the moment you arrive on site — no extra trips to the supplier, no missing components. Whether you're cutting drainage swales, finishing parking lots, or grading foundations, the RL-200 2S delivers the accuracy and reliability Topcon is known for across the construction industry.

System Overview & Jobsite Applications

Unlike single-slope or self-leveling horizontal lasers, the RL-200 2S lets you set independent grade percentages on both the X and Y axes simultaneously. This is essential for applications like parking lot drainage, road crown grading, and agricultural land leveling where true two-axis control determines the quality of the finished surface. The laser's wide operating range and robust housing make it equally at home on a rough grading operation or a finish grade pass before paving.

Job Applications

Parking Lot & Flatwork Drainage: Set simultaneous cross-slope and longitudinal slope to ensure positive drainage across large paved surfaces — critical for ADA compliance and long-term pavement performance.

Road Subgrade & Base Preparation: Establish consistent crown or superelevation across roadway sections with repeatable accuracy, reducing rework before paving crews arrive.

Foundation & Site Grading: Control cut-and-fill operations across commercial building pads where tight tolerances on both axes prevent costly drainage corrections after construction.

Agricultural & Land Leveling: Achieve precision field grades for irrigation efficiency on large acreage where two-axis slope control maximizes water distribution uniformity.

Frequently Asked Questions

Can the RL-200 2S be used with a machine control system?

The RL-200 2S is a manual dual slope laser and is not natively designed for fully automatic machine control. However, it is compatible with the Topcon RC-400 wireless remote for grade adjustments from equipment. For full machine control, consider Topcon's MC-series systems.

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

The RL-200 1S allows slope on one axis only, while the RL-200 2S provides independent slope control on both the X and Y axes simultaneously. The 2S is the correct choice for any application requiring true dual-grade or cross-slope work.

Is the LS-100D receiver included in this package?

Yes. This complete package includes the Topcon LS-100D digital receiver, which provides precise grade indication with both visual bar display and audible signals, making it easy for a single operator to work efficiently without a second crew member at the instrument.

How do I maintain accuracy on the RL-200 2S over time?

Topcon recommends periodic calibration checks using a known benchmark or the two-peg test method. The RL-200 2S has a ±5° self-leveling range, but always confirm the instrument is within that range before each setup. Annual service by an authorized Topcon dealer ensures long-term accuracy.
