Tool level is a thing necessary thing for any repair, including redecorating. Moreover, people need it in other cases too: for example, while hanging shelves. You need at least two levels of different types while building structures, including suburban buildings: for example, a hydro level for laying the foundation, and a bubble level for mounting walls and roofs. Let's describe the types of the tools, which you can easily find on Aliexpress.
What are the building levels?
The design is based on a liquid chamber with a measuring scale. The deviation from the horizontal plane is determined by the division of bubble in the tool. The two-chamber level also allows you to control the deviation from the vertical; the three-chamber level will help you to get the angle of 45. There are models with movable cameras that can be used to adjust any angle of inclination (for example, when designing truss systems).
Additional devices can be provided in the design of the level-magnets for fixing on the surface, etc. Sizes are very different: from half of a meter to three meters. It is better to have models of different sizes for mounting elements of different sizes for large-scale construction. The cost of these tools is rather small, it is convenient to use, and the measurement accuracy is quite high.
While choosing a bubble level, pay attention to the mounting of the liquid chambers. The best option is built-in non-removable (the flasks on the screws are quickly loosened, which make the measurement process more difficult). The measuring scale, the risks on it, and the position of the bubble should be clearly visible.
Tip: it is better to test the tool directly in the store. If you put the tool level on the counter and then turn it 180 degrees in the same place, the measure should match.
These devices are characterized by the highest accuracy and the highest price. The price of such a cheap level will be higher than the professional bubble level. The functionality of these devices is much greater: the functions of scanning directions, a range of up to 100 meters, etc.
The best goods of the type are produced by BOSCH. These devices are quite expensive, that’s why the purchase is necessary only in the case of large-scale development. A cheap model can be bought on Aliexpress.
This one we have bought by ourself. The model is perfect for home. It was used in three repairs. We were built a new internal partitions in the apartment and a balcony.
That is a highly specialized tool level, which is suitable only for displaying the horizontal plane. It consists of a hose, which is up to twenty-five meters long and two water chambers with a measuring ruler. There are no such services on Aliexpress. Therefore, you will have to look for the tools in the nearest stores.
Levels of this type are used for working in outdoor conditions, for example, while installing foundations. A distinctive feature is the requirement for temperatures: the water used for measurements must be at room temperature. So, you couldn’t get the correct result near the heating tools, when it’s cold or hot. That’s why you should keep it in mind.
Make sure that there are no bubbles, while filling the chambers with water.
Moreover, there are also tube levels (including folding modifications) that are close to bubble levels. So, the ordinary smartphone apps for the appropriate purpose are also suitable for simple household needs.
