The Spectra Precision UL633 Universal Laser is the first construction laser allowing total automatic control of all three axes (X/Y/Z).

It is a fully functioned, high accuracy dual grade laser that has the ability to lies on its side, in a trench or above ground, to be utilised as a pipe or alignment laser.
Control of the Z axis (pipe mode) is accomplished through the new "fan beam" technology. The UL633 can align the plumb beam automatically using the optional SpotFinder SF601 target 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 and the Spot Finder offer additional versatility for 90 degree layout applications on concrete pads as well as indoors for drywalls.

Activating the SpotLok mode ensures the UL633 locks and holds the plumb beam automatically to the Spot Finder at the desired direction or elevation point offering a precise alignment to avoid rework.

With a 'mm' display laser receiver and a 2-way fully fuctional remote control, grade and drainage work has never been so quick, precise and easy.

PlaneLok
The PlaneLok function (Y- or X-axis) automatically locks onto an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather

GradeMatch
The automatic Grade Match (Y- or X-axis separate) measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, time spent searching for grade plans, and over excavating.

Automatic Axis Alignment
This unique feature allows precise automatic axis alignment to a desired point without positioning the receivers 90° perpendicular (+/-40° alignment range on Y- and X-axis)

Axis Masking
Axis masking eliminates interference with other crews on the jobsite. In this mode, the user can "shut off" any of the 4 glass windows, making the laser emit from just one or two, in direction of their work.

The RC603 remote control supplied with the UL633, offers the advanced automatic features like Grade Match, PlaneLok and Automatic Axis Alignment.
The remote as well as the HL750 'mm' display laser receiver, has an intuitive graphic display which is back-lit for ease of viewing.
Contractors can do everything with the remote control that they can do at the laser keypad, up to 100 meters away even from the cab of a machine.

The Spectra Precision UL633 dual grade laser is covered by a 5 Year manufacturers warranty.

Once shipped from the manufacturer, Accurate Instruments' Calibration and Service Centres check and adjust all instruments on collimators and ranges, then fit them with the appropriate shockwatch, calibration sticker and issue a test calibration certificate.

Shockwatches a damage indicator that alert the user whether the instrument has been dropped.

The Spectra Precision UL633 is checked, calibrated and certified by Accurate Instruments then fitted with a shockwatch.
