Building levels are used to measuretilt horizontal and vertical surfaces. With the help of these tools, markup is made for the construction of various structures, furniture assembly, application or laying of finishing materials. Neither the construction nor the repair can not do without a level.
To decide on the choice of tool, let's first understand what types of levels exist.
First of all, it is a water level.Its other name is hydro level. It is used in cases when it is necessary to find irregularities in the arrangement of horizontal surfaces, since his work is based on the main feature of the water surface: always take the same position - horizontal.
Hydro level is a sleeve, lengthwhich can be from five centimeters to several meters, at the ends there are flasks with applied microscale. Building levels of this type have both advantages and disadvantages.
A plus is their ease of operation andlow price, and minus the fact that such a tool can be used, working only with horizontal planes. It is not allowed to store it near radiators. The water in the sleeve should not have bubbles, otherwise the readings will be erroneous.
Most often masters use levels of building bubble type. Such a device consists of a body in which flasks with liquid are located.
If there is only one flask in a level, thenthey are determined by the error of only horizontal planes, with two flasks - both horizontal and vertical. If there are three flasks, then this device also determines the magnitude of the turning level. Usually the bubble levels are rectangular. Their length can be from 20 centimeters to 2.5 meters, and telescopic models - up to four meters.
Often beginners are interested in how long the construction level should be. 2 meters or less is the optimal size.
The body level is usually made of polystyrene or of light metals, such as aluminum. The liquid in the flasks is alcohol.
Bubble levels available for saletype - magnetic. This is a bubble tool, only with magnetic inserts. Very handy if you work with metal, as it is easily attached to metal surfaces.
Did you find what you need in the store? And how to check the level of construction? Everything is very simple.
Place the instrument on a flat surface.This provision should be noted in order to put the second testable instrument on the same place a little later. At the level there are divisions, so the bubble is likely to shift to one of them. We must remember to what. Turning the level, put it in the old place, which we noted a little earlier. If the bubble “leaves” in the same direction, which it deviated the last time, it means that the level works perfectly. If not, continue to choose.
Recently, on the shelves of constructionmarket appeared laser levels of construction. These are very accurate tools, but they have a flaw - this is their value. If accuracy is paramount for you, such a device is what you need. Accuracy provides a laser beam, the length of which can reach up to one hundred meters.
