Topcon RL-H5B Self-Leveling Laser PS.DB Kit with LS-80L Receiver, Grade Rod 10ths and Tripod - 1035257-01 (uses Alkaline Batteries)

Overview

The Topcon RL-H5B Self-Leveling Laser PS.DB Kit (1035257-01) delivers reliable horizontal leveling for general contractors, landscapers, and commercial builders working on grade-critical projects. This complete package includes the RL-H5B laser head, LS-80L receiver with rod clamp, aluminum grade rod marked in 10ths, and heavy-duty tripod—everything needed for elevation transfer, foundation layout, and site grading work. The alkaline battery design eliminates charging downtime on remote jobsites, allowing crews to swap fresh D-cells in seconds and maintain continuous operation. Topcon's self-leveling mechanism with motorized pendulum automatically levels within ±5° and shuts down if disturbed beyond acceptable tolerances, preventing costly measurement errors during concrete pours and excavation tasks.

Frequently Asked Questions

Can the RL-H5B be used for vertical plumb applications?

No, the RL-H5B is horizontal-only. For plumb beam or dual-axis work, consider the Topcon RL-SV2S dual-grade laser or RL-VH4DR combination system with vertical mode capability.

What's the difference between the PS.DB kit and standard RL-H5B packages?

The PS.DB designation indicates this kit includes both alkaline battery capability and the DB (dry battery) holder, plus the complete package with LS-80L receiver, grade rod, and tripod. Standard packages may include only the laser head or rechargeable battery options without the full accessory set.

How do I know when the laser is properly leveled and ready to use?

The RL-H5B self-levels automatically within 4-5 seconds after power-on. A solid green LED indicates successful leveling and rotation. If the unit is tilted beyond ±5°, the laser beam shuts off and the LED blinks red, requiring manual repositioning of the tripod to bring it within leveling range.

Can this laser be used in bright outdoor sunlight?

The visible red beam is detectable with the LS-80L receiver in full sunlight at typical working distances (200-400 feet). For maximum range or extremely bright conditions, position the laser in shaded areas when possible, or upgrade to the LS-100D receiver with enhanced detection sensitivity.
