How Does a construction laser Work

Levels are one of the most essential pieces of equipment in any builder’s toolbelt. Engineers and construction workers can’t do without a good level, either — but fewer of these professionals are relying on the traditional form of the tool. Instead, many have replaced their old level with a construction laser level. This tool performs the same task as the original tool, but it does so with greater accuracy and a smaller footprint, too. Here’s what you need to know about finding a new construction laser.

The Tech Behind Laser Levels

Laser technology is explained succinctly by its own acronym — Light Amplification by the Stimulated Emission of Radiation. Laser levels rely on the use of a focused, amplified light beam that is emitted from a diode. A diode is a solid-state semiconductor device that converts electrical energy into light. The result is a strong light beam that can be used to create a straight guideline.

Laser Level vs. Traditional Level

Traditional levels — also called bubble levels — are different from laser levels in several ways. The first differentiation is the level (no pun intended) of accuracy you can expect. Laser levels are more accurate than their traditional counterparts. In terms of calibration, both types also require effort from the user, but laser levels are again typically the superior option.

How to Use a Laser Level

Understanding how a construction laser works is only part of the equation. You also need to understand how to use one correctly. Luckily, the process is not particularly different than using a traditional level. One of the biggest benefits of the laser level, in fact, is its ease of use. If you are using a self-leveling laser level, you should place it on a surface that is already level and allow the unit to calibrate. Once this is done, it can be used as a normal level would be.

Square, Level, and Plumb

You need a construction level that can accurately project guidelines that are square, level, and plumb. To check that a corner is square, you may project dual guidelines from a laser level and ensure that the corner intersects the projections. To check that a line is level or plumb, you may similarly project a horizontal or vertical guideline, respectively, and ensure that your line intersects.

Types of Laser Levels

There are three main types of construction laser levels to choose from, including:
  • Plumb
  • Line level
  • Rotary
Each of these functions slightly differently. It’s up to you to determine which type is the best construction laser for the job you’re working on.

Frequently Asked Questions

How do I calibrate a laser level?

How Does a construction laser Work

A laser level should be calibrated approximately every six months, and the exact protocol for doing so depends on the model of level you’ve chosen. Consult the manufacturer’s guide to find specific instructions regarding calibration.

Are all laser levels self-leveling?

No. Some laser levels require the user to level it manually through use of a traditional level for comparison. This can be advantageous for users who wish to ensure absolute accuracy.

What is a laser level’s self-leveling range?

The self-leveling range of a laser level refers to the value of its difference from the internal level. If the laser guide indicates that a laser level can self level within four degrees, for example, you know that a level beam can be produced within a range of four degrees.

Are there any risks associated with laser levels?

When used properly, there are no significant risks associated with a laser level. It should be noted, though, that improper use can result in eye exposure to laser beams, which does pose a hazard to users.

Are there any drawbacks to a laser level?

The aforementioned risk of injury with improper use is the greatest drawback of laser levels. It is also difficult to use laser levels outdoors in bright weather because the laser is usually difficult to view in such conditions.

Find Level Ground With a Laser

A construction laser is one of the best investments you can make if you regularly need to measure level ground or otherwise use a level. If you’re looking for the best selection of laser levels and other engineering gear, you’ll find it at Engineer Supply. Call (800) 591-8907 to find the right laser level for you.

If you’re ready to purchase this level, be sure to pick yours up at Engineer Supply.

#2: Topcon 32x Automatic Level AT-B2

Best construction level topcon-32x-2110220B0

This automatic level will allow surveyors and construction professionals to get accurate level, angle, height and distance measurements. The optics have a 32x magnification, a 1/32-inch accuracy, and a built-in compensator that will stabilize the line of sight (even in the presence of fine vibrations that can be caused by heavy equipment on the job site). The telescope has a focus range of 7.9 inches and can be used in confined spaces. It also has an internal magnetic dampened compensator, which will allow you to level the line of sight within a range of 15 arc minutes at an accuracy of 0.3 arc seconds. You can even get it with the following accessories:

  • Diagonal eyepiece.
  • Optical micrometer.
  • Light pack (which can be helpful low-light conditions).
  • 40x eyepiece (which will improve accuracy and magnification).

#3: Sokkia B20 32X Automatic Level

Best construction level sokkia-B20-32X-2110120B0

This construction level has been proven to provide both precision and durability. It also features enhanced reliability in all types of environmental conditions. Its tough and compact body has an IPx6 Rating. So, it will be resistant to damage caused by water, humidity, and dust. It also has a number of useful features, which can include but may not be limited to:

  • Precise and reliable automatic compensator — It has four high-tensile suspension wires and a magnetic dampening system, which will ensure accuracy and stability (even when it’s exposed to temperature changes, vibrations, or shock).
  • Superior telescope — It can provide an exceptionally bright and sharp view that will minimize eye strain. It also has an ultra-short focus of 7.9 inches (20 cm) from the end of the telescope, which makes it easier to use in confined spaces.
  • Quick collimation — The two knobs of endless horizontal motion drives can be operated with either hand, which allows for faster and easier aiming.
  • Horizontal angle measurement — Horizontal angles can be read in one-degree or one-gradian units, and the freely rotatable circle will allow you to perform any angle reading from zero.
The stadia lines on the reticle will allow you to perform any distance measurement, and it’s easy to adjust with one screw. The circular level vials are adjusted with two screws, but both of them are quick and easy with the provided tools.
