Rotary Laser Test - Comparisons. Com 2024

Lasers are not completely safe, so they are divided into different classes. The rotating lasers with which we are in our Rotation laser comparison from Test-Vergleiche.com are to be classified as non-hazardous and not to be confused with laser pointers that dazzle enormously and damage the eyesight. However, displaying lines on a wall is like this Rotary laser cheaper as a laborious measurement and weighing with a spirit level. The alignment of pieces of furniture or the boundary lines when painting are so much faster representable, as with any other technique.

Rotary lasers are preferably used as construction lasers. Our comparison is one at the same time Construction laser comparisonby learning how to handle such a handy device.

Everything is in balance with a rotating laser

A rotating laser or laser emits a laser beam that throws an exactly horizontal or vertical line against a wall. On Bosch Professional Rotary Laser can even do that all around, in the 360 ° angle.

And this is how a rotating laser works:

The laser beam generated inside the rotating laser is deflected by a prism. It is a pentagon prism, i.e. a prism with five corners that deflects the laser beam by 90 °. The prism rotates around its standing axis. This ensures that the laser does not just appear as a point on the wall, but that a continuous line is projected onto the wall. So you can with a Rotary laser favorably and quickly create a reference line.

Depending on the model, this reference line can be displayed horizontally, vertically or at a specific angle. The height of the line can be with a Rotary laser receiver, also called detector, either read or displayed at wavelengths in the visible range on a yardstick. In most cases, a horizontal reference line is used, which is also called horizon animals. This can be set manually or fixed automatically with a tilt compensator. An adjustable angle allows the laser beam to be precisely adjusted, aligned horizontally or vertically. For independent Feinhorizontierung are the most Rotary laser self-leveling.

The range of best rotary laser is at max. 500 meters and the accuracy is usually ± 5 to 10 mm on 100 m length. If such a rotating laser is required in plant construction for the exact installation of machines, the accuracy is up to ± 0,1 mm on 100 m length (0,001mm / m). These are absolute professional rotary lasers, which are not the subject of our comparison.

What does a rotary or construction laser do?

A construction laser plays a major role, especially in the construction industry. With it straight lines at buildings or heights are measured. It is not rangefinder which fulfills other tasks in the construction industry. Horizontal and vertical measurements can be made with a construction laser. For particularly high quality Professional construction lasers you can even set a precise angle. Thus, for example, allow measurements of angles of inclination, such as on pitched roofs. On Rotary laser with tripod is best used for this. The tripod consists of a tripod on which the construction laser is rotatably mounted. There is also Rotary laser mounts for wall mounting.

So go ahead

If you want to measure a building or a plot of land, you must first determine a horizontal plane by which to align the rotating laser. All measurements are now made in relation to this line. If an angle is required that deviates from the horizontal line, this can be adjusted with angle-adjustable models on the prism.

For height measurement, you need a leveling staff that must be perfectly vertical. If the laser beam strikes the Nevellier lath, it marks the exact height of the Baulasers. For a double measurement, the location of the crossbar and the laser can be exchanged. As a result, a deviation in height can be determined. Your rotary laser works largely automatically, it adjusts itself and aligns with the horizontal plane.

How should the rotation laser be set up?

A rotating laser can be placed at any X-site. As you are with yours Rotary laser the best Results can vary greatly depending on the correct layout. A badly or incorrectly set-up laser provides inaccurate measurement data. An optimal footprint offers reasonably soft soil Baustrahler with tripod be firmly anchored in the ground by its three legs without the tripod can slip. On asphalt or concrete the construction laser can slip away. Small rubber pads help prevent the tripod from slipping. In addition, choose the parking space in such a way that you have all the measuring ranges in view, otherwise the construction laser has to be constantly changed over and readjusted.

Pull the tripod legs to the desired length for comfortable use. Attach the legs with the attached screws. Now the rotary laser can be put on and screwed on.

How do you need to adjust your rotation laser?

The most important task when setting your construction laser is leveling. With the circular level it can be roughly adjusted. These serve two screws that can be moved in opposite directions. Now turn your construction laser to 180 °. If the Bubble bubble is still in the dial, the laser is optimally aligned. In the opposite case you have to readjust.

Can the laser beam harm the eyes?

A rotating laser is usually easy to operate. An on-off switch is sufficient. But beware: a few safety issues should be considered. Send in color Rotary emitter green or red light off. Laser radiation can cause serious damage to the retina of the eye. Therefore, certain safety regulations apply to all laser devices. The rotation laser offer is fortunately offered with a laser power that can not cause any damage. Nevertheless, you should not refrain from wearing laser safety goggles when operating. You should avoid looking directly into the laser and restore your laser correctly when not in use. In the Rotation laser rating of the laser classes, the models are mostly in laser class two. This is sufficient for smaller construction sites or indoors. Class 2 is the right one if people could unexpectedly get caught in the laser beam. A brief exposure is harmless to the eye, but its intensity is sufficient to cover a distance of up to 30 meters. For longer distances, up to 500 m, a Construction laser receiver part thats it!

An overview of the individual laser classes can be found in the following table:

Which rotary laser equipment features are there?

The best rotating laser is just good enough for the craft. Craftsmen need a variety of functions, pay special attention to performance, range or battery life. To operate you need one Rotary laser experienceOn the other hand, you can operate rotary lasers for do-it-yourselfers without special prior knowledge. Below you can familiarize yourself with some of the features. Not every rotary laser is equipped with all the following functions Rotary Laser Bestseller but should own most of them.

• To switch on and off
• Control via remote control
• automatic leveling
• manual leveling
• automatic mode
• tilt function
• manual tilt around an axis by ± 5 °
• Mark vertical surfaces
• Plumb function
• point operation
• Vertical leveling
• Rotation and scan function

The do-it-yourselfer or homeowner, who just wants to build his kitchen cabinets or build a carport, is satisfied with a builder who has few of the above features. If you have one Construction lasers favorable then pay attention to a good cost-benefit factor. For painting, laying tiles or building furniture it is also rewarded with a discontinued model Rotary laser reduced to acquire. On Cross Line Laser may or may not do it digital protractorwhen it comes only to laying tiles or attaching cabinets in the solder. Good things do not necessarily have to be expensive, and such a model is still better than a pencil and spirit level.

Is there a Stiftung Warentest Baulaser test report?

Unfortunately we do not have one Rotary laser test found at Stiftung Warentest. Such, partly commercial devices are unfortunately rarely the subject of an investigation. Even the magazine "Self is the man" could not help us here. So you have no other choice than your own Rotary laser test winner to choose.

And finally ...

A rotating laser is a true helper for the construction site, home or garden. If you need a flexible device for your measurements and the highest precision, you will be well served by a rotary or construction laser. A rotating laser creates vertical and horizontal lines or construction points by means of a laser arc, which it projects in an 360 arc. This allows for simultaneous projection on the floor, ceiling and wall, allowing greater accuracy than any other measurement method. With the help of these laser measuring instruments, all renovation or construction work in the private as well as in the commercial sector can be done faster.
