Topcon RL-HV2S Self-Leveling Dual Grade Laser Complete Kit with LS-100D Receiver, Tenths Rod and Tripod / Rechargeable

Set Two Independent Grade Planes — Simultaneously

The Topcon RL-HV2S is a professional-grade dual slope rotary laser built for contractors who can't afford to re-run setups or chase grade errors across complex sites. With independent X and Y axis grade control, this unit lets you establish a full two-directional grade plane in a single instrument position — the kind of capability that separates production-grade site work from guesswork. Whether you're a grading sub, a civil crew chief, or a general contractor managing drainage-critical pours, the RL-HV2S delivers the accuracy and range to get it done right the first time.

Overview & Jobsite Applications

The RL-HV2S pairs a high-accuracy dual slope laser head with Topcon's proven self-leveling platform, giving you a working range of up to 800 meters in diameter and grade capability on both axes simultaneously. The included LS-100D machine control and hand-held receiver integrates seamlessly for both manual staking and machine-mounted applications. The rechargeable battery system supports extended operation without the hassle and cost of disposables. This complete kit is ready to work the moment it arrives on your jobsite — no sourcing accessories separately.

Job Applications

Parking Lot Construction: Set a two-directional cross-slope in a single setup to meet ADA drainage requirements without repositioning the instrument between bays or drives.

Road Crown & Superelevation: Dial in opposing slopes across a road crown or transition to superelevated curves without switching instruments or recalculating intermediate grades manually.

Drainage Channels & Swales: Establish a running longitudinal grade and a lateral cross-slope simultaneously to ensure positive drainage flow direction on every shot.

Slab-on-Grade & Flatwork: Control both fall directions for sloped concrete floors in warehouses, wash bays, and agricultural structures where single-axis lasers fall short.

Frequently Asked Questions

Can the RL-HV2S set grade on both axes at the same time?

Yes. The RL-HV2S independently controls grade on the X and Y axes simultaneously, which is what makes it a true dual slope laser. You can set, for example, a 2% longitudinal fall and a 1.5% cross-slope at the same time from a single instrument position.

What receiver is included and is it compatible with machine control?

The kit includes the Topcon LS-100D, which functions as both a handheld grade rod receiver and a machine-mounted detector. It's compatible with most aftermarket and OEM machine control systems that accept a standard laser input signal.

How long does the battery last on a full charge?

Topcon rates the RL-HV2S at up to 40 hours of continuous operation on a fully charged NiMH battery pack. Real-world runtime varies with temperature and rotation speed setting, but it's designed to handle full production days without mid-day recharging.

Is the RL-HV2S weatherproof enough for outdoor site use?

The RL-HV2S carries an IP66 rating, meaning it's fully protected against dust ingress and resistant to high-pressure water jets. It's built for outdoor contractor use in rain and dusty conditions — not just occasional light exposure.
