Topcon LS-100D Laser Receiver


Topcon’s latest addition to its line of compact digital laser sensors — the LS-100D. The sensor digitally displays the offset value to on-grade, which is designed to help make elevation and vertical alignment control easier and faster for any application.

The LS-100D features an extra-wide beam capture sensor that also rejects annoying interference from strobe light exposures.  The large and bright LCD displays (front and back) feature 9-channels of grade information and digitally display the distance to on-grade. By pressing the hold button, the display is locked so the user can conveniently read the results.

The sensor offers three colored LED’s and a magnet mount for vertical operation, which is designed to be useful for steel erection or operator grade-checking while excavating. Alert icons appear on the LCD if the accompanying Topcon rotating laser instrument is disturbed (HI alert) or when the laser battery is low.

Supplied with the bracket and batteries.
