Spectra Precision UL633N Dual Grade & Pipe Laser

The world's first construction laser allowing total automatic control of all three axes, the Spectra Precision UL633N combines dual grade functionality, automatic dual grade axis alignment with trench and pipe laying setout.

The Spectra Precision UL633N is a world first. It is a combination of an automatic dial-in self leveling dual grade laser and an automatic target finding pipe laser.

With similar standard features as the GL622N the UL633N model will additionally perform dual slope matching at the same time whilst the plumb beam can be changed into a rotating fan beam which can be detected by the SpotFinder SF601. The UL633N can align the plumb beam automatically to the SpotFinder for pipe laying and trench applications.

Measuring a grade value through an existing pipe or an open trench can also be done quickly and easily in automatic Spot Match mode. The UL633 includes a full-function remote control, with a built-in back-lit intuitive graphic display. Contractors can do everything with the remote control that they can do at the laser keypad, up to 100 m away.
The UL633N is supplied as standard with two HL760 “mm’ display laser receivers, which can communicate together.

The Spectra Precision UL633N comes standard with a 5 Year Manufacturer's warranty covers any defects in materials or workmanship.
