Level in the home is often called the "level". You need to hang wardrobe, make home repairs or to build a modern building? All this will be difficult without leveling.
My first "level" line resembled a flask of liquid: and uncomfortable to wear, and the options are limited. Modern levellers are capable of much: surveyors and builders use them to erect a building, plasterers line the walls, and office workers hung shelves, calendars and pictures. How to choose the right device for any occasion, and I'll tell you, and at the same time offer my personal Top 5 of the best leveling and answer the most frequently asked questions.

Best level: Buyer's Guide
What are Levels
There are two classifications of these devices: on the accuracy of measurements and on the principle of work.
As they can be, depending on the accuracy of:
- Technical. Suitable for the determination of the terrain or for small home repairs. Admit the quadratic error between 2 and 10 mm for 1 km double stroke.
- Exact may be mistaken for 0.5 - 2 mm.
- Precision not afford a deviation of more than 0.5 mm.
Accurate and very precise leveling instruments are mainly used for construction, where the slightest error depends on the strength of the building.
Different models have different leveling principle of operation:
- geometric used VIZIR horizontal beam which shows the difference in the location of points on the terrain. Points have to designate special racks. Measurements carried out with one or more provisions.
- trigonometric (Also known as theodolites) - more complex devices. Need if you want to learn the height difference between selected points. Thus leveling instrument measure the distance to the point and the angle of inclination, the data obtained is used in a special formula to calculate the excess.
- hydrostatic - two liquid containers connected by a hose. We put vessels at two points and see whether the same level of water in them. Irregularities shows fine, but the working distance is limited.
- Optomechanical - Tools for the pros. It operates using a light beam and rails, which are placed in a special way. With this tool, you can align the structure in the horizontal plane to the millimeter, but to work with it requires special knowledge.
- laser - simple and convenient. Their bright beam perfectly shows the levels of the points and entire planes. They can be simple or complicated professional household.
- digital - the latest technology including leveling. The measurements made by laser or optically and output digital data. Can remember and even analyze the information. Cons - a decent rate and sensitivity to shocks.
Optical levels and their "shock absorbers"
Inside the optical levels are glass prisms and a movable mirror. Mobility need a mirror to the device showed accurate results even if it is not level. But the mirror can be displaced from the vibration near the construction sites, subway, and so on. N. To avoid this kind is inserted in leveling shock absorber, which is called the damper.
Air damper pushes airflow, sandwiched between two plates. Magnetic removes vibration magnetic field. Experts say that the second option is faster.
Types of laser levels
The market offers many models with a laser beam. Which to choose?
- linear - the simplest and most popular. Form a clear bright line, on which it is convenient to do the layout.
- rotary a rotating head equipped with two lasers. Help align the various planes. Perfect for decorating.
- point It works both horizontally and vertically. They are convenient check point on the ceiling.
- combined can be projected up to five different lines: left, up, right, down or vertically. Work and linear and point.
- builders planes not only determines the difference in height, but also designs different types of planes. It is expensive, so use it professionals.

FAQ
How to use the leveling instrument?
That the instrument gave accurate advice when dealing with them need to follow a few simple rules:
- Install and securely on a flat solid surface, but rather on a tripod.
- On the path of the beam should not be any interference.
- Do not try to exceed the maximum operating distance. If the instructions given to 30 meters, then at 35 the results will be inaccurate.
- The laser beam is hazardous to the eyes. Work with them in special glasses, alert the others, especially children.
Why do I need a compensator in the leveler?
Due compensator sight leveling shaft is always horizontal. That is, this arrangement compensates for the slope. With the compensator can make accurate measurements when the surface is unstable under the tripod or uneven.
Where can I buy?
To purchase the appropriate level, no longer need to go around dozens of shops. A variety of models of modern levels can be ordered through the Internet without any problems.
