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 60-70% 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 .00012 in/ft. (0.01 mm/m or 2 arc secs) in a 180°/360º sweep and .00006 in/ft. (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.

Automatically Rotating Laser Planes with 200 Ft. (60 m) Range

The L-730 Leveling Laser System is a highly accurate and affordable leveling laser alignment system that measures flatness or levelness of surfaces or machinery as well a straightness of machine axes.  Unlike other “point-n-shoot” lasers, the L-730’s laser beam continuously rotates, which allows the use of multiple targets simultaneously.  The laser plane has a measuring range of 100 feet (30 m) in radius, or 200 feet overall.

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 a guide as to how accurate flatness/levelness measurements can be made.

The L-730 features a continuously rotating laser plane that is flat to .00012 in/ft. (0.01 mm/m) in a 180° sweep. 

  • L-730/L-740 Laser Plane Measuring Capabilities

High-Accuracy Leveling up to 70% Fastwer

The L-730 features 2 built-in level vials, accurate to .00016 in/ft. (0.015 mm/m).  By using multiple A-1519/A-1520 Wireless Targets, multiple surfaces or points on a machine can be leveled at the same time.  This saves up to 70% over using conventional levels or optics.

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.

Wireless Targets with High Resolution and Measuring Range

To measure the flatness of a surface, the L-730 system uses our wireless targets (A-1519-2.4ZB and A-1520-2.4ZB) that feature up to .00002 in. (0.0005 mm) resolution, large measuring ranges of up to ± .55 in. (±14 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 like all Hamar Laser systems, the targets provide real-time alignment data so misalignment errors can be fixed without changing the setup!

Plane5 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.
