There would be a suitable length, and all other parameters of the tool takes into account. While the roulettes are divided into many parameters, including the rigidity of the web, according to the measurement accuracy. After all, they are produced from various material with varying degrees of protection. The quality of the tool largely depends on these factors. In this article, we will look at various options for measuring roulettes.
Measuring tapes and their accuracy
It is not a problem to purchase a measuring roulette today, a matter of how to buy an accurate and high-quality tool, because, as a rule, in stores an abundance of a wide-quality bulpotreb, which can be used only in domestic purposes. The roulette of high quality and imported production will cost several orders of magnitude more expensive, because they are being carried out in accordance with the wishes and requirements of the world specialists. And accordingly, it is possible to buy such a professional and high-quality tool only in specialized corporate stores where a construction tool is sold.
When choosing a roulette, you should pay particular attention to what lines are applied to the markup tool. Surely, many have noticed how fat and thick lines a scale on measuring tape measurements is marked. It is difficult to decide on what edge of the line, and may be in the middle, measurements should be performed. Then how professional roulettes, intended for the production of more accurate works, have a scale made by thin lines, see which a person with poor eyesight is difficult. The only way out here can be the contrast and the use of large numbers.

And one more lack of cheap roulettes. Cutting a web of the measuring tape measure on its markup at least into pieces of meter length, you can make sure that all parts do not match. In this case, each subsequent part will be somewhat more than the previous one. It is quite clear that it is simply impossible to work with the use of such a tool.
The degree of rigidity of the roulette canvas
Many masters, picking up a measuring roulette, pay attention to the form of the canvas of this tool. Most often, it is performed completely directly or semicircle, bent along the entire length. It should be noted that the curved canvas has a greater rigidity and is not worked out if there is a need for a large roulette release. A high-quality measuring tape measure can be climbed only after release two meters. This fact can play an important role when carrying out repair work, as it makes it possible without any help to perform the appropriate measurements on large areas.
Length of measuring roulette
This parameter is relatively understood. Choose the length of the measuring roulette follows from the upcoming production work. For example, for work in apartments or homes, there will be a tight-length tape measure. Then, on the scale of construction sites, it is best to use a roulette, having a length of 50 m and even more. In other cases, the use of laser roulette is considered to be appropriate, its maximum measurement range is 300 m.
Roulette tape protection
In the production of the measuring tape measure, it can be covered with a protective layer, which protects the tape from the possible effects of corrosion. A cheap tool remains almost unprotected, as it is difficult to call the defense of a thin layer of paint that is applied to the tape.
Measuring tapes having a high cost - about 10-15 dollars, have a more serious coating. Some of them cover zinc layer, and some copper. This roulette is characterized and according to the method of applying paints, scales, as well as a protective layer, which allows to significantly extend the service life of the instrument.

However, it is often unnecessary zeal of manufacturers is not fully justified, because the tool takes such a serious protective layer, increases the weight of the roulette web. As a result, the canvas can be overwhelmed already when stretching it on the length of one and a half meters.
What should be the roulette housing?
An experienced master can evaluate the quality of the roulette only by its corps. Obviously, most of the roulettes having a length of less than 20 meters and made in a plastic case are unlikely to differ in particular reliability. Special attention should be paid to the outlet, in the event that it is equipped with an insert from sufficiently dense, but soft rubber, the web is guaranteed protected from the appearance of possible scratches during the operation resulting from friction of the body of the body. In addition, the roulette canvas is covered in expensive and reliable protective layer.
On imported, which means high-quality measuring tape measurements, even the clamps that play the role of only clamping mechanisms, while changing the tape are arranged. In this case, as a result of braking, friction is not subject to tape measure, but a special drum to which it is wound.
There are also a number of other features of measuring roulettes. For example, electronics that is built into the roulette housing. In the work of work, it is impossible not to note the convenience of this device, because it can very quickly show the measured distance, exactly to the tenths of the millimeter. Such roulettes in production pass special comparative testing and belong to high accuracy tools.
Increase the accuracy of the desired measurements will help and the presence on the roulette of the bubble level, which will allow it to be used to control, for example, brick masonry.
Thus, despite the seeming simplicity, choosing a roulette should be very carefully and then she will serve you for many years.
