L-730 Precision Leveling Laser

Hamar Laser’s L-730 Precision Leveling Laser System is one of the most accurate and easy-to-use leveling, surface flatness and straightness measurement system on the market today. It features an automatically rotating laser plane that is second in accuracy only to the L-740 Ultra-Precision Leveling laser. It also features large-range, wireless targets and built-in 3 arc second level vials. Continuously rotating laser planes and the capability to use multiple target sensors at the same time let you level machinery 2 to 3 times faster than laser transits, theodolites or levels.

System Highlights

  • Fast: Aligns large machining centers up to 70% faster than traditional methods or interferometers.
  • Easy: Multiple high-resolution wireless targets with a range of up to 100 ft (30 m) provide real-time alignment data, so alignment/leveling errors can be fixed without changing the setup.
  • Accurate: Precision laser planes have a flatness of 2 arc seconds (.00012 in/ft or 0.01 mm/m) in a 180°/360º sweep and 1 arc second (.00006 in/ft or 0.005 mm/m) in a 90º sweep.
  • Versatile: Flatness, straightness, leveling and parallelism measurements of almost any horizontal or vertical surface.
  • Smart: Powerful Windows-based Plane5 software, combined with advanced wireless interfaces, makes collecting and analyzing alignment data fast and easy.

L-730 Leveling Laser Alignment System

The L-730 Leveling Laser System is the most accurate and affordable leveling laser on the market today. That is, of course, if you do not consider our L-740 Series of ultra-precision lasers.

Extremely Flat Laser Plane

One of the critical components of any laser system is the straightness or flatness of the laser beam or plane, as this is the reference from which the measurements are made.

The L-730 features a continuously rotating laser plane that is flat to 2 arc seconds (0.00012″/ft or 0.01 mm/M) in a 180° sweep and 1 arc second in a 90 sweep. It also features 2 built-in levelvials, accurate to 2 arc seconds, and an operating range of range of 100 feet (30.5 meters) in radius.

Two Configurations for Many Different Applications

The L-730 Scan Laser System is ideally suited for a whole host of alignment applications. The L-730 comes in 2 configurations. The standard L-730 has a horizontal laser plane, for checking flatness and leveling. The L-730W has a vertical laser plane and is used primarily for aligning the straightness of a rail or saw.

New Line of Wireless Targets

Another critical component of flatness or straightness measurements is the resolution laser beam detector. This determines how close the measurements can be made.

The L-730 system uses our line of wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to 0.00002 in. (0.0005 mm) resolution, large measuring ranges of up to 1 in. (25 mm) and 2.4 GHz “Zigbee” radio wireless communication with our R-1357-2.4ZB PDA Readout, which can simultaneously display up to 5 targets.

These lightweight targets are all powered by rechargeable batteries and can be used as digital height gages when used with precision inserts. And like all Hamar Laser systems, the targets provide live alignment data so misalignment errors can be fixed without changing the setup!


For alignments with tolerances of 0.00015″/ft or (0.01 mm/M) or greater, the L-730’s applications include:

  • Checking the flatness of almost any surface (squares, frames, ways, flanges, circles, etc.)
  • Measuring and leveling machine beds and ways, large bearing surfaces, and fabrications
  • Checking way twist and parallelism between horizontal surfaces
  • Measuring surfaces up to 200 feet (61 meters) long with 1 setup


Flatness Software

For wireless recording and analyzing alignment data, our color, 3-D flatness and squareness analysis software, Plane5, simplifies and streamlines the data analysis process. It can measure up to 7 different surfaces in one project setup file and present a color, 3-D graph of the flatness and squareness analysis for each surface.
