Topcon RL-H5B Rotating Laser Level

Topcon RL-H5B Rotary Laser Level

Professional Self-Leveling Solution for Construction Elevation Control

The Topcon RL-H5B represents the perfect balance of precision, durability, and value for contractors who require reliable elevation control across mid-sized construction projects. This professional-grade self-leveling laser delivers dependable performance in challenging job site conditions where accuracy directly impacts project success.

Efficient 400m Diameter Coverage

Unlike basic rotating lasers with limited range, the RL-H5B provides complete elevation control across an impressive 400m diameter job site from a single setup position. This extended reach eliminates time-consuming multiple setups on medium to large projects, increasing your team's productivity while maintaining consistent ±20 arc second accuracy throughout the entire work area.

Rapid Electronic Self-Leveling Technology

Construction schedules demand efficiency, and the RL-H5B delivers with push-button simplicity that gets you working within seconds of arrival on site. The sophisticated electronic self-leveling system automatically establishes perfect level across a generous ±5 degree range, compensating for uneven mounting surfaces without manual adjustments or complex setup procedures.

Outstanding Performance and Durability

The RL-H5B sets the standard for field endurance with up to 100 hours of continuous operation using standard D-cell batteries. This exceptional power efficiency ensures uninterrupted work through multiple shifts and remote deployments where power access is limited. When job site disturbances occur, the system automatically re-establishes correct level without operator intervention, maintaining measurement integrity even in high-vibration environments.

Weather-Resistant Construction

Engineered specifically for construction environments, the RL-H5B features an IP66 weatherproof rating that provides complete protection against dust ingress and resistance against powerful water jets from any direction, ensuring reliable operation during unexpected weather changes and continued performance in heavy rainfall conditions.

Ideal Applications:

• Residential foundation excavation and leveling
• Commercial site preparation
• Drainage slope verification
