Topcon RL-SV2S — Professional Dual Grade Rotary Laser for Demanding Job Sites
The Topcon RL-SV2S RB Kit delivers the precision and reliability that grading crews, concrete finishers, and site contractors demand on complex dual-slope projects. Built and calibrated in Japan to Topcon's exacting standards, this kit pairs the RL-SV2S rotary laser with the LS-100D laser receiver and rechargeable battery system — giving your crew everything needed for a full day of uninterrupted, high-accuracy grading work right out of the box.
Dual Grade Laser Built for Complex Site Work
Managing two independent slopes simultaneously is no simple task, and the RL-SV2S is purpose-built for exactly that challenge. Whether you're establishing cross-fall on a parking lot, setting drainage grades across a retention pond, or fine-grading a road crown, the RL-SV2S delivers independent X and Y axis grade control with a wide slope range that covers virtually every civil and commercial grading scenario. The self-leveling design automatically compensates for minor setup variations, so your crew spends less time checking the instrument and more time moving material.

- Rechargeable Battery Pack (RB) — eliminates AA battery cost and downtime on long grading shifts
- Battery Charger — standard charger for the included rechargeable pack
- Carrying Case — durable molded case for transport and storage
- Alignment Sight — for quick, accurate instrument orientation on setup
- Tripod Attachment Adapter — 5/8" x 11 thread compatible
Job Site Applications
Parking Lot & Commercial Flatwork: Set dual cross-slopes across large concrete or asphalt pours and maintain consistent grade without multiple setups. The RL-SV2S holds both axes simultaneously so finishing crews stay productive across the entire slab.
Site Grading & Drainage: Establish positive drainage grades over retention areas, detention basins, and stormwater channels where a single flat plane simply won't work. Independent X/Y control makes compound slope work straightforward.
Road Crown & Subgrade Prep: Set crown grades on roadway subbase preparation. The wide operating range means a single instrument setup covers long stretches of roadway without repositioning.
Agricultural & Land Leveling: Slope fields for surface irrigation efficiency. The extended battery runtime and rugged IP66 housing keep the RL-SV2S running through long field days in dusty, wet conditions.

Frequently Asked Questions
- Does the RL-SV2S work with machine control grade rods?
- Yes. The included LS-100D receiver is compatible with standard grade rods used in machine control and manual grading applications, making it versatile across both hand-grade and equipment-mounted setups.
- What is the difference between the RB and standard RL-SV2S kit?
- The RB designation indicates the kit includes a rechargeable battery pack instead of standard alkaline batteries. This reduces long-term operating cost and is ideal for crews running the instrument across full work days without access to battery resupply.
- Can the RL-SV2S be used in rain or dusty conditions?
- Yes. The RL-SV2S carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to powerful water jets. It is designed for active outdoor construction environments in variable weather.
- What is the maximum slope the RL-SV2S can project?
- The RL-SV2S supports a grade range of ±10% (±5.7°) on both the X and Y axes independently, which covers the vast majority of civil grading, drainage, and site preparation applications.
