How to choose a laser level or level - the characteristics of the variety and selection criteria
If you build a house without using measuring devices, you get everything wrong, and he did not stand for long.It is known by our ancestors, and be sure to check the horizontal and vertical plane of the absence of error.They used those devices that were in those days.Of course, these devices can not be called perfect, but that others were not.We were lucky more - is now available for each master level, working on laser beams, carrying out measurements quickly and accurately.About how to choose the level of the laser so that it is the right moment did not disappoint and suits your needs, you will read below.

Aboutlaser level: the principle of operation and characteristics of
This mechanism is used for measuring thin and bright laser beam.For his appearance is going to the special design of the diodes.By the way, the laser light originally used only by the military.Then, after a fairly long period of time, it came to medicine, and then gradually be introduced in other areas of our lives, it has been used in industry and construction.
housing lasers consists of plastic.It inserts are latex or rubber, which do not allow liquid or dust get into a precision instrument.It is not cheap at all levels and on building on it, and the sand can get into, and cement, and water, and drops of paint.Therefore, the protection of housing is vital to this device.
use laser levels can be both on site and in the apartment for domestic needs.Manufacturers produce these devices of various kinds, so you can always find a suitable laser level, focusing on the tasks to be performed with its help.
Advantages of this type of devices:
1. Measurements made with them, are quite accurate: the error of one meter is not more than a few tenths of a millimeter.
2. point or line, perfectly visible, much easier target mark, which is equipped with ordinary Levels.After all, this line can be run immediately, without markup, for example, dropping it on the construction equipment.
3. lightning device takes measurements, the work is not necessary to cook it enough to get it out of the case and all.
4. By placing the unit horizontally, you can not worry about the future: he will make the measurement, and very quickly.
5. not need to be an expert to work with lasers - with him cope anyone.
6. not required for the measurement of several working - device operated by one person.
In general, laser level - is not nothing but a more modern descendant of all the other instruments for the measurement: theodolites, tape measures, levels, ordinary leveling.Check it in any vertical and horizontal surfaces that require compliance with accuracy.Knowing how these devices are classified (in fact different species have different names and even purpose), you can get quite a distinct idea of how to choose the laser level according to their needs.

varieties and types of laser levels
1. EDM , known colloquially laser tape measure - the most simple device.
Builder - in everyday life is called "laser level" or "laser level".
2. Static builders.
- Static builders lines (other names - krosslayner or multiprizmenny Builder)
- Static builders axes (other names - pointer, point the laser).
3. Rotary builders , building the plane (other names - mnogoprizmenny Builder, level).
Builders static type
Typically, these devices are used in the construction and decoration of flats, facades, small portions.
Krosslaynery produce rays, which are static line.These lines are produced by passing a laser beam through a special prism and splitting it, not by rotating the laser beam about its own axis.Typically, these split-rays is not got - twenty meters, not more.If the builder to use a special receiver, it is possible to increase the range to fifty or even hundreds of meters.The high-power LEDs and design, the further extend the rays.
Example of krosslaynera.
Since diodes and used multiple prisms, then the builders called multiprizmennymi.There is, however, a simple model, where there is only one beam vertically or horizontally.But they are few.Basically, these two beams: vertical and horizontal.It turns a cross from the laser beams.In complex models are several lines and crosses, but there are those that can be used as a plumb line, they shine up (zenith) or bottom (nadir).
angle scanning lines of standard builder hundred and twenty degrees.In the more "cool" models it is one hundred and sixty degrees.The greater the angle, the larger the additional intersections of lines.It happens so that all the three hundred and sixty degrees are used (when lines are connected in a full plane).
In krosslaynerah usually happens integrated self-leveling system, the pendulum or electronic type.To be accurate readings by a conventional bubble level, the device aligned horizontally.Pendulum compensator instantly a unit so that its plane is parallel with the ground.And while working on the sly is compensated shifts and tremors.This makes the system of self-regulation.The maximum permissible angle to compensate for many of the laser levels is three degrees.Although there are models where this angle is five and six degrees.
If the angle is greater than this value, the automatic signals that need to manually adjust the position of the device.This can be done by using a twisting legs, but you can move to another location device.When the plane or the line is not strictly required horizontal and vertical and inclined, you can turn off automatic, hoping only for themselves and adjusting the position of the device manually.
marking the walls with the help of builder lines mounted on the wall.
These devices are also called dot lasers.They do not have a source which rotates or prism system, therefore they give only a point indicating the desired direction.But these points can be seen much better than the previous line type builders.This is particularly evident when the sunlight is blinding bright.After all, the builder of the axes of prisms, beam blanking is not available.Therefore, when deciding which laser level to choose for a very large room, get such a model - you will not regret.And in the street to work with it will be comfortable.
An example of the laser spot.
Such a device rays three or five.They are directed up, forward, down, left and right, respectively.The dotted lines perpendicular to each other are obtained.Such a device can be marked formwork projections floors, frames, partitions and walls.Sometimes these instruments called laser plummet, that does not give a complete characterization.Zenith can be obtained by placing the device on the floor, and the nadir - lifting it to a tripod.

Rotary builders, creating a plane
In these devices, the light beam is not scattered by a prism and rotates, thereby forming a plane.In general, it is a pointer to point-type rotary powerful laser.The range of the device is very good, so it is often used in construction, where the impressive square.While indoors (especially large ones) such builders as it is possible to successfully apply.For example, this level can be verified by laser surface supporting structure.In addition, Rotary Builder can create a laser beam is directed to the zenith.Very comfortable with such a device to measure the difference between the heights.
Example of rotary builder.
If, in addition, does not cost any devices, the range of the laser beam of this device ranges from fifty to seventy meters.If you use a receiver (usually bundled), it increases the range of fantastic: up to three hundred, and even up to four meters.Sensitive receiver catches beam on a construction site and gives this signal.
Typically, lasers allow you to adjust the speed of rotation of the beam.Emitting head can be made to spin at a rate of from ten to six hundred revolutions per minute - it's a solid range.And adjustment helps to reduce the consumption of power, leaving his life more complete.And the functionality of the device, the possibility of adjustment, substantially increases.
product markup by using a rotation builder.
Builders with a rotating beam can form a horizontal plane, or may be adjusted to the tripod, and showing a vertical plane and angles.But on the latter, inclined planes, we can speak only when the model is very "advanced".In this case, the canceller horizontal position simply disconnected by acting manually.Although there are models where one axis is compensated, and the other exhibiting a manual method in some cases it may be useful.
There rotary builders with remote control, duplicating buttons on the unit.It is convenient - you can control the device, moving away from him at a considerable distance.Also, all the rotary leveling is a function called "out of level".It does not allow to mark something wrong.

Choosing a specific model: 9 Tips
Well, the main types of laser levels we considered, it now remains to go to the parametersdevices, which should pay particular attention.And let's talk about what can limit the functionality of such a device, as a construction laser level.
Council 1. very important indicator is the error of projection.So, buying the market on the cheap laser level manufacturer unknown, do not rely on its accuracy.Up to three (!) Millimeter for every ten meters would be a mistake, but it's a lot.If you buy a more expensive model, besides a good brand, the error does not exceed one or even just half a millimeter.Rotary builders more accurate.When purchasing be sure to check what the error of the dispenser.
Council 2. range (visible and scanned), otherwise, the range of - are also significant.Usually well-known companies are figures understate.As you begin to use it - the result of a lot better.But it's a good idea, because the opposite would have been much worse, agree.The size of the working area, which is important for rotary devices from different manufacturers is calculated differently.Here, look, on the radius or diameter in question.Some firms may write the first, and the other - the second.If you buy a static Builder, to ask if he could work with the receiver.Even if the receiver is not complete, it is good that such a possibility was.
Council 3. studied in detail in the passport characteristics of the laser device.This is its wavelength, power and class.The most common laser wavelength shestsot thirty-five nanometers of.It has a beam of red color with a small zheltinkoy.The green beam more powerful, bright and nice looking - its wavelength is five hundred thirty-two nanometer.Previously we used more lasers with a wavelength of six hundred and fifty nanometers, but now they have removed from production.
Council 4. Another important point: self-leveling features.Not a very good option is to limit the angle of three degrees.Better, of course, if the angle is five degrees.Also, the passport indicates the time for which the compensator is adjusted.Naturally, the smaller it is, the better for the user.In addition, it is sometimes necessary to turn off the self-leveling device - must be such a possibility in a good instrument.This is necessary, for example when working on a slope or when moving the device.
Council 5. Now the power supply.It was he who determines how long the device can be operated without interruption.Static Builder runs on batteries or battery-fingers no less than ten hours.To save battery, disable unnecessary rays.As for the rotation of the laser need more power, the rotary devices penlight batteries will not manage.They work on alkaline, nickel-cadmium or nickel-metal hydride battery.When this capacitance is important for the charging device, and its speed.Rotary Lasers can work without a break from twenty-five to forty hours.
Council 6. Ambient temperature required for normal operation, as shown in the passport.Models leveling professional type of trusted vendors may work in the cold (at minus twenty degrees) and heat (with plus fifty degrees).Also, pay attention to indicators such as the temperature, the allowable storage device - usually is a temperature range greater than required for the job.Do not confuse these two values.
Council 7. protected case is different, it can be easily identified by the marking.Thus, the standard defense - marking IP54 - will give you the opportunity to use lasers on a dusty construction site, and in the rain.In order to protect the unit in case of a fall, it equipped with damper plates.In addition, there is also important quality of the housing material and its ergonomics.For example, the company produces models of Spectra Precision, where the passport indicates that the device did not happen, even if dropped from a meter - and a half.Naturally, provided that the level is fixed to a tripod.
Council 8. Options.What is attached to the laser level, except for the leveling, and everything is needed for the job?Thus, with the device are available:
- bag or case;
- special glasses to help see the laser beam;
- remote control;
- several flat targets;
- device for charging batteries or batteries;
- clips or magnets to attach the unit to the ceiling or wall;
- geodesic rake;
- receiver to intercept the beam.
Council 9. manufacturers.In the first place in the rankings, you can put a company BOSCH.It should be noted that the laser level Bosch appreciate and professional builders, and home of the master.Prices for household and professional appliances of this brand may be different from each other very much, but the quality of even the cheapest model is excellent.
Condtrol The company also produces a very good laser levels and levels.They, of course, a little inferior to the products of the previous manufacturer, but have a very nice price.The company Matrix, experts say, lets not very good professional levels, but domestic models on her height.Products brand Kapro, both professional and personal, it is better to use in the room.There they showed themselves well, on the street - is worse.It was not clear moments?
