L-730 Basic Leveling Applications

Flatness and leveling laser

General Leveling

For basic leveling applications, you won't find a better, faster or more accurate way of aligning surfaces to earth level than the L-730 Precision Leveling Laser. That is, of course, unless you decided to invest in our L-740 Ultra-Precision Leveling Laser, which is 4 times more accurate!

The L-730 was designed for those leveling applications that require about 0.00015"/ft (0.013 mm/M) accuracies or higher. It is an extremely portable and yet affordable alternative to traditional leveling methods like theodolites or transits. Its automatically sweeping laser plane and large-range targets with 0.001" (.025 mm) resolution create a powerful tool for quickly aligning almost any surface or machine bed .


Very Flat Laser Plane and Highly Accurate Levels

The L-730 Laser produces a laser plane that is flat in a 180º sweep to within 2 arc seconds (0.00012"/ft or 0.01 mm/M). In a 90º sweep, the laser plane is flat to within 1 arc second. That means that under good atmospheric conditions, the L-730 is accurate to +/-0.0006" (0.016 mm) in 10 feet (3 meters) or +/- .006" (0.15 mm) in 100 feet (30.5 meters). The L-730 has 2 level vials built right into the laser that are also accurate to 2 arc seconds.
 

Live Alignment Data

As with all Hamar Laser products, the L-730 Precision Laser Leveling System provides live alignment data. This means you can put a target over a jacking bolt and start adjusting it and the reading automatically updates.
 

Multiple Targets for Large Applications

You can even use more than one target, which is extremely useful on large surfaces or machine beds. In fact, there is no limit to the number of targets that can be used. This allows the use of multiple work crews, which can really speed alignments.


Minimal Training Needed

The L-730 is so easy to use that it usually only requires 1 day of training, unless our Plane5 software is purchased, which only adds 1 day of training. Compared with optics where training can last up to 2 weeks, the L-730 can significantly reduce the time critical technicians are out of action when being trained.


Wireless Targets and Readouts

Wireless Targets and Readout Speeds Setup

Our 2 new lines of wireless targets eliminate long extension cords for reference targets. The targets work with all of our continuously rotating laser plane systems and can be used up to 100 feet (30.5 meters) from the laser.

The first target line (A-1532, and A-1533) features: built-in readouts, 0.001" (0.02 mm) resolution and up to 3" (75 mm) of measuring range.

The second line (A-1519-2.4ZB and A-1520-2.4ZB) features: wireless communication to a Nomad Ruggedized PDA (R-1355-2.4ZB), which can display up to 5 targets simultaneously, resolutions down to 0.00002" (0.0005 mm) and up to a 1" (25 mm) measuring range. Other features like electronic zeroing and target averaging help to speed alignments.


New Targets Can Measure Actual Dimensions

The dimension from the bottom of new targets to the center of the target cells have been tightly controlled. This allows the targets to be used with precision inserts to measure actual dimensions from the laser plane to the surface being measured.


Color Windows Software

S-1388 Plane5 SoftwareThe L-730 can also be linked to our new Plane 5 flatness analyzing software. It is a Windows based software that can analyze almost any layout for flatness or straightness. Plane 5 will even analyze squareness if used with our squareness lasers (L-743, L-742, L-741, L-733 and L-732). Squares, rectangles, frames, circles, rings, and up to 5 sets of ways can all be easily analyzed with Plane5. The alignment data can be automatically downloaded by using the A-1519-2.4ZB target and A-910-2.4ZB receiver for the laptop.
