Topcon Rotating Laser Level Red Beam Dial-Dual-Grad Rechargeable RL-SV2SRB + LS100D

TopconSKU: 313990772




RL-SV2S Rotating Laser Level

Designed for a wide variety of applications, the Topcon RL-SV2S is Australia’s number 1 construction dual-grade laser. It can be used for horizontal, sloping and vertical laser applications. Slopes up to ±5% can be used in either the X or Y axis. Turn on its side and use it for layout and alignment applications.

The RL-SV2S excels in long range operation. Need to shoot elevations up to 400m from your laser? No problem! This instrument has the power and range to cover a 800m (diameter) jobsite.

With efficient power usage, the RL-SV2S has a long battery life. The unit also gives you the option of two forms of power, 120 hours of continuous usage with D cell (4 x) batteries (not included), or 65 hours with the included rechargeable battery pack (RL-SV2S-RB model).

The RL-SV2S is “jobsite tough” and with its IP66 rating, the unit can withstand dust, a sudden shower and even torrential rainfall. Topcon stands behind this reliable and accurate laser with a 5 year guarantee which is the best factory warranty in the industry

LS-100D Digital Receiver

Versatile and designed for maximum user convenience, the Topcon 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 coloured 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 battery is low.
