Today on the Mister Worker® Blog we are going to talk about laser measuring with Edoardo Riva, Stanley Black & Decker’s Marketing Manager.

For many years, laser technology has been present in many sectors: from medicine to communications, from manufacturing to the construction industry. In this latter context, laser levels are fundamental. 

What is a laser level? 

A laser level is a tool typically used in the construction sector to accomplish leveling, measuring, and alignment tasks. This tool features a laser beam projector, that emits a high-visible red or green line (or dot) onto a surface. 

How to use a laser level?

Using a laser level may seem complicated, but it is a fairly simple process once you are familiar with the device. Here is a step-by-step guide on how to use this tool:

1. Preparation and safety:

  • Make sure you have a good quality laser level and are fully charged or with working batteries.
  • Wear safety goggles to avoid eye damage from laser light.
  • Check your surroundings and make sure there are no obstacles that can interfere with the projection of the laser beam.

2. Positioning:

  • Decide where you want to project the laser beam. For example, you may want to level an area to hang a picture or place a shelf.
  • Place the laser level on a stable, level surface, such as a table or a suitable stand. Some laser levels come with brackets or magnetic mounts for easy installation.

3. Power on and settings:

  • Turn on the laser level and select the desired settings, such as horizontal mode, vertical mode, or both.
  • Some laser levels allow you to adjust the tilt or rotation of the laser beam. Set the desired angle if necessary.

4. Alignment and projection:

  • Position the spirit level so that the laser beam is projected onto the surface you wish to work on (e.g., a wall).
  • Adjust the position of the level until the laser line aligns with the desired position. You can make small adjustments until you get the perfect alignment.

5. Verification and adjustments:

  • Use a ruler or other measuring tool to check that the laser line is perfectly horizontal or vertical, depending on your needs.
  • If necessary, make further adjustments to the position of the spirit level to achieve the desired accuracy.

6. Actual work:

Once you have properly aligned the laser line, you can proceed with your work, which could include installing objects, drawing painting guidelines, or any other task that requires a level surface.

7. Turning off:

After you have completed your work, turn off the laser level to conserve battery power.

Remember that specific instructions may vary depending on the model you are using. Be sure to carefully read the user's manual to get detailed information on settings and proper use.

What is the advantage of a laser level?

Using a red beam or green beam laser level provides the following advantages:

  • An enhanced speed and efficiency in the process of carrying out measurements, which leads to an increase in productivity with an acceptable precision tolerance;
  • Higher flexibility, since these tools can be placed on a tripod or a wall, which gives you more freedom to do other activities;
  • Better comfort, as these means are lightweight and easily transportable;
  • An immediate reading of the values thanks to the easy-to-read digital displays,
  • A precise and high-visible laser light.

What is the best brand of laser level?

Stanley is considered a leading brand in the market of laser measurement, as it offers a very wide range of products, able to satisfy all professional needs. From tape measures to laser levels, the brand has the right tool for everyone. Regarding Stanley laser levels, their ranges vary from 300 meters in radius for rotating lasers, with an accuracy of 1.5mm at 30 meters, to 10 meters for indoor lasers, with an accuracy of 4.5mm at 10 meters. The tool should be selected according to the application and it must guarantee the most accurate results.

Are laser levels more accurate than traditional models?

For many people, laser levelling technology applied to the construction sector allows for greater precision with respect to analog instruments. 

However, that is not true. A traditional instrument, such as the optical level (for example the Stanley 1-77-160, 1-77-245) or a simple plumb line, can be more accurate than a laser level. It is in fact with traditional tools that the precision of laser levels is tested. 

Which is better red or green laser level?

Many professionals ask themselves “Is red or green laser better?”. When comparing the two types of lasers, green beam lasers (like the Stanley STHT77594-1 or the STHT77592-1 cross-line laser level) are the best option for the following reasons: 

  • They emit a brighter and sharper line. So, these lasers are more visible in a wider range of situations, such as illuminated open areas, allowing you to work easier and get accurate results. 
  • Green lasers have a larger working range than red ones, and, therefore, they are perfect for working on construction sites.
  • Green laser levels are made with more parts and components and are characterized by better laser diodes than red.

Is a green laser level worth it?

Are you looking for a laser level that offers a laser line visible from a distance with the utmost clarity? Look no further: the answer is green. Although a Green Beam laser level may involve a slightly higher initial investment, its advantages become clear as you work. With these models, you will benefit from perfectly sharp lines, effortless usability, and undeniable convenience that will make your tasks a breeze. Moreover, you will enjoy an incredibly precise performance, along with increased productivity. No more squinting or straining: just pure visibility and precision. Your projects deserve the advantage of green.

What laser level do I need?

When buying a new laser measurement tool, it is important to have in mind what to consider. Here are some factors that make a high-quality laser:

  • Accuracy: precision is fundamental while carrying out construction activities since the smallest mistake can be fatal.  
  • The brightness of the point or of the line: both in red beam and green beam models, the brightness of the color is essential, because it is easily recognizable, even at a great distance.
  • The stability of the track: regarding electronic self-leveling levels, the electric engine should adjust as quickly as possible. In the case of a laser with mechanical self-adjusting, this function is carried out by a pendulum with magnets which dampens the oscillations. In both cases, the speed of execution and the stability of the line or point are significant, and they represent the good or bad design of the laser. The main function of these tools is to speed up the execution time: a long time of adjustment may decrease or cancel the benefits.
  • The size of the point or the line. The thinner they are, the better. When we have to mark a track, we do it in the center of the line. The thicker the line, the higher the chance that the marked track is inaccurate.
  • The warranty provided by the manufacturer: most of all, the existence of an “after-market” service is fundamental, because it grants to the customer technical assistance also after the standard warranty has expired. Stanley and DeWalt chose to provide a service of maintenance and calibration of their products thanks to a laboratory operated by the company’s employees. 

Moreover, it is better to choose your laser level according to the application field:

For a furniture maker who has to place wall units in an indoor environment, a self-levelling laser is suitable for the purpose and, more in general, such an instrument is suitable when the distance between the laser and the line produced is under 2 or 3 meters. Some examples of self-leveling lasers are the Stanley Cubix™ STHT77499-1 with green beam and the STHT77498-1 with red beam.

In the case of work on large surfaces, a rotating laser with a receiver which can operate up to a distance of 300/350 meters will be necessary. Some examples are the Stanley models FMHT77446-1, FMHT77448-1, FMHT77447-1, FMHT77449-1.

What are the main developments in the world of laser measurement in recent years?

Companies have been orienting production towards meeting the needs of the operator as best as possible. A good example is a multiline laser with green beam. The cross lines and the great visibility of the green beam allow the user to immediately identify the points where to place the necessary elements. The classic example is the uprights for plasterboard walls. One such product to consider is the Stanley multiline laser level FMHT1-77356. It projects green rays intersected at 360deg, in order to guarantee extremely accurate markings on different surfaces. The lines emitted by this model are four times brighter and 30% sharper than traditional red beams. Moreover, this item offers a working range of 35M (maximum 50M with a detector), an accuracy of +/- 3mm @10M, as well as +/- 4° self-leveling capacity.

What should I do before working with a laser level?

In order to obtain the best results, you should follow these pieces of advice:

  • Read the instruction manual. Having an understanding of how the product works avoids mistakes, speeds up the use, and increases security. 
  • Control the calibration. In the event of falls or severe temperature changes, precision may be affected. Check the calibration of the laser following the instructions, it’s a simple and quick action that avoids mistakes and consequent damage.
  • Connect a suitable battery to the tool according to the instructions 
  • Find the best place to position your tripod, if you need to use it while working with your laser level. Make sure the ground is not slippery so that the tripod doesn't move from the position established.

If there is a discrepancy with the indicated tolerance, you should contact the assistance center.

Are cheap laser levels any good?

In terms of quality, low-cost laser levels are generally not as reliable as their more expensive counterparts. Cheaper models can have a variance of about 1/8 inch per 33 feet, while pricier options tend to have a much lower deviation, less than ±1/13 inch per 33 feet. 

We recommend that no expense be spared in choosing your laser level. Remember, an accurate, quality measuring instrument is a profitable investment in the long run. Besides, a job done right is worth the money spent!

How to calibrate a laser level?

To calibrate a laser level, you need to place the laser level on a tripod, mark a reference point on a wall at a distance of at least 100m, and adjust the instrument according to the height of the point that has been established on the wall. Various laser-level tripods can also be found in our store. One of these is the Stanley 1-77-13 model, which is extendable from 90 to 173mm and features highly robust aluminum construction. The extendable elements can also be locked using a high-quality locking system.

Are there security issues while using laser instruments?

Regulations state that there are different classes of lasers between 1 and 4 depending on the output power. 

For what concerns classes 1 and 2, there’s absolutely no risk of eye or skin damage. In any case, it is good practice never to stare at the light source for a long time, exactly as it’s not suggested to stare directly at a light bulb. Stanley and DeWalt use exclusively lasers pertaining to class 1 or 2.
