The Topcon RL-H5A Horizontal Self-Leveling Rotary Laser is a multi-purpose laser that is ideal for grading, excavating, site preparation, concrete works, and other general construction projects. With a laser receiver, it offers a long operating range that covers up to 800m in diameter. This laser level also offers an accuracy of up to ±1.4 mm at 30m and is self-leveling within ±5 degrees.
For added precision and accuracy, the RL-H5A features manual single-axis slope and rotates 600 times per minute. This horizontal rotating laser is simple to use, intuitive and re-levels itself immediately if the device is disturbed on the job.
With an IP66 rating, the Topcon RL-H5A series is protected from dust and low-pressure water jets. This rotary laser uses either a dry cell or a rechargeable battery that can power the device up to 100 hours, making it the great companion for a long day at work.

SLOPE VS GRADE, WHAT IS THE DIFFERENCE?
A Slope Laser has buttons to allow the user to tilt the laser over to an angle, however there is no display showing what the angle is. This is ideal for creating slopes where the actual angle does not matter (ie. water run-off on a driveway or pad). Some models allow single axis only and others allow dual axis slope.
A Grade Laser has the same function, however there will be a display which will show the exact angle (usually as a percentage grade), so you can dial in the exact angle required and the laser will tilt over to that gradient. Some models allow single axis only and others allow dual axis grade.
