Goniometers capable of high precision calculations

The protractor is an accurate instrument that allows you to measure the angles of inclination of surfaces in relation to each other. Such information is necessary for the installation according to the drawing of planes, elements of various structures, parts, as well as component parts of equipment. Some goniometers are capable of making high-accuracy calculations over a considerable distance. All measurements are made in degrees using a special scale equipped with a mechanical pointer. This definition works for both the vernier and the electric display, whose usage depends on the type of device.

Characteristics of inclinometers

By definition, an inclinometer is a device designed to build a plane parallel to the horizon. If there are additional elements on the device, it can be used to determine vertical lines, in accordance with the readings of a plumb line, or specified angles of inclination. This device is otherwise called a level and is divided by design type into:

• bubble;
• optical;
• water;
• laser.

It is noteworthy that in order to increase the functionality on some devices, elements are used that characterize two types of inclinometer at once. An example is a bubble level equipped with a laser pointer (or two), which allows you to mark a given point (or line) instantly and at a considerable distance.

The equipment of individual inclinometers includes several measuring instruments at once, which makes it possible to increase their functional characteristics. Such devices are used to make complex calculations with several input parameters. They find their application in the construction of structures of complex geometric configuration.

The most popular goniometers 2022

The most actual, for today, the direction of use of goniometers is construction sites. There are angles of all kinds of sizes and degrees of inclination that need strict adjustment. Here, each element needs to be clearly positioned relative to the surrounding space, and it is impossible to provide template accuracy with an ordinary eye. Therefore, goniometers of various designs are used for measurements and calculations, capable of providing accurate data in any conditions.Among the top sellers for 2022, there are several models.

Popular goniometers 2022 designed for narrow specialization

In addition to construction, goniometers are used in many other specialties where the accuracy of flattening is important. Measurements with these devices are important in joinery and carpentry, because deviations in the alignment of their products can lead not only to problems in operation, but also to domestic injuries. In addition, goniometers are used by physicians, topographers and even astronomers.

However, in this situation, narrow specialists use devices of a different design. For the technique of their measurements, there is no need to use multifunctional equipment. But the requirements for the accuracy of matching angles for this group of professionals are much higher. For this reason, they use devices that are not structurally related to inclinometers in their work. Such devices are divided into several groups:

Nonius device

The measuring device is applied to the plane in the place where it is necessary to measure the desired angle, while the ruler and the body of the device are superimposed on the sides of the angle. Next, you need to count the degrees located on the main scale, to the point of contact with zero on the vernier field, in order to determine the degrees. Then, moving along the vernier scale, they find a division that matches the desired mark on the main scale, lining it up in a common straight line to determine the minutes.

optical instrument

Here there is a movable ruler, which must be moved in such a way that it forms the required angle with the fixed part. After that, a special ring is fixed, which is used for clamping.Further, it is necessary to take into account that both the disk and the magnifying glass of the device depend on the moving element in construction, and, therefore, the desired position is determined from them. Through the magnifying glass, the movements of the markings of the disk are observed, combining it with the mark on the plate, after which the readings of the device are taken.

Electronic goniometer

This is a device that has a digital indication necessary for measuring angles. For convenience, each arm of the fixture was provided with markings that allow you to set the exact value for the marks on the contact planes. The electronic device of the goniometer has special functions that allow both resetting and freezing the results obtained, which adds convenience to work. At the same time, the accuracy of the device is at a fairly high level, the error is only 0.3^about (degrees).

Pointer goniometer

This is the name of a goniometer-quadrant, equipped with an elongated guide, on which a scale is applied. Such a device has found application when cutting large slabs. It is used to measure both internal and external angles from 0 to 180^about (degrees). Such devices are made of stainless steel or ordinary steel with an anti-corrosion coating.

Recommendations

Inclinometer designs equipped with automatic systems allow you to navigate faster and perform more complex actions even in cramped conditions. For example, an electronic goniometer is ready to report the measurement result immediately after the rulers touched the surface. At the same time, the optics need to be initially installed on a horizontal surface to avoid level errors.And mechanical devices additionally require certain knowledge from the performer in order to be able to make calculations.

For this reason, the most popular and widely available are goniometers equipped with a large number of different options. When buying any measuring device, it is necessary to check the regulatory documents in order to be able to check or adjust it.
