Topcon RL-H5A Rotating Laser Level Kit is the next generation of self levelling construction Lasers. With a high accuracy and a long range, the RL-H5A is simple to use for checking elevations. Proven reliability on any job site with long-range consistency and ease of use.

With electronic self-levelling, you press the power button and go right to work in seconds. If the RL-H5A gets disturbed on the job it relevels itself automatically. The self-leveling motors are accurate to ±1.5 mm at 30m.

The instrument has the power and range to cover a 800m diameter job site.

The RL-H5A gives you the option of up to 60 hours of continuous usage with the rechargeable battery pack or 100 hours with (4) D cell batteries.

With the IP66 rating, the RL-H5A is “job site tough” and can withstand dust, a sudden shower and even torrential rainfall.

Include this Topcon LS-100D Detector with Digital Readout (mm/inch). Shows the mm/inch scale to see the elevation or drop on the display e.g 10mm - 8mm - 5mm - 2mm - LEVEL. Includes Holder 110.

Included in the RL-H5A purchase price is a 5-Year Guarantee. Topcon is backing up this reliable, accurate laser with the best factory warranty in the industry.

Detector features

Kit includes LS-100D Detector & Bracket:

Versatile and designed for maximum user convenience, the LS-100D features a digital readout to confidently deliver elevation and vertical alignment control on demand.
It features an extra-wide beam capture sensor that also rejects annoying interference from strobe light exposures. The large and bright LCD displays (front and rear) feature 9-channels of grade information and digitally show the distance to on-grade. By pressing the Hold button, the display is locked so the user can conveniently read the results. For added versatility, three colored LED’s and a strong magnet mount are embedded for vertical operation, ideal for steel erection or operator grade checking while excavating.

To assist in monitoring the Topcon rotating laser, alert icons appear on the LCD if the instrument is disturbed (HI alert) or when the laser battery is low.

User guides & Datasheets

Do you need ShockWatch® adding to your Laser?

The optional ShockWatch impact indicator clip is a tamperproof, mechanically activated device that turns bright red to indicate mishandling or after the Laser has received an excessive impact. Designed to mount directly onto the Laser Level, the clip is compact and economical and provides 360° impact detection alerting the user to check the Lasers Calibration before use. If this option is selected, our Technicians will fit your Laser with a Shockwatch prior to dispatch, giving you and your users extra piece of mind on the job site.
For further details of ShockWatch®, please Click Here.

Need to mount a Detector on Plant equipment?

The Topcon RL-H5A can be used for machine control by using a magnetic CR700 Detector, which can be purchased as an "upgrade" or as an optional extra.

Need Help?

I have worked in the construction industry for over 25 years dealing with hundreds of suppliers, the quality of their products is fantastic, the delivery is next day so you can't complain about that and the customer service is second to none, if you need a leveling tool don't bother going anywhere else.
