Measuring equipment in the hands of the builder is the same as a scalpel in the hands of a surgeon. I affirm this without exaggeration. Construction and repair work is just the area where the results of measuring work are very important. And errors made during construction due to improper measurements can cause huge losses, or even cause the tragedy.
Today, there are a lot of modern devices at the disposal of builders. Special section — laser electronic meters. Laser meters — rangefinders, plumb line, angular, levels, levels — are very convenient and useful. In addition to the main task — actually measuring actions — they have many different auxiliary functions that provide the opportunity not only to record data, but also to remember it, to make calculations here, transfer them to a computer. As for the most important purpose, laser measuring devices are convenient in that they make it possible to measure the most inaccessible objects, because when measuring using such devices there is no need for physical contact with the object of measuring operations. Measurement in a remote way is now no less, if no more correct than with direct contact with the object of measuring work.
Laser rangefinder
Operating such devices is absolutely easy. The most primitive — rangefinder. It is enough to bring the rangefinder to any point on the object, the distance to which you should find (wall, pillar, tree trunk), press the button — and the results are instantly displayed on the range of the rangefinder. The laser level at the beginning of work requires the use of ordinary mechanical bubble levels in order to install the device in the desired position. After that, the laser level can independently build horizontal and vertical planes.
But laser plumb line does not need preliminary preparation of the correct position — they immediately know how to calculate the measure of the deviation of the object from a given vertical.
Perhaps the most difficult to use are laser levels. These are modern optical devices operated to determine the height difference between points. The device works due to the fact that the laser beam rotates with a high frequency and gives a visually vertical or horizontal plane. Such devices are used mainly when conducting external measuring works.
But in general, use laser appliances, comrades, they can significantly facilitate your work. Of course, the laser ruler costs more than a conventional roulette. But in the second case, the participation of the second person is necessary for measuring work. And this, by the way, is also worth the money.
