Levels Bosch Professional

All products manufactured under the Bosch brand have proven themselves from the very best side. Levels were no exception. These measuring devices come in a wide variety of modifications, each of which has a wide range of functionality. Such equipment is needed to measure heights and planes and is used to solve professional and domestic tasks.

For surveyors and construction workers, a measuring level is considered a must-have device - thanks to it, they can carry out all the necessary measurements and make calculations with maximum accuracy. Most often, when carrying out work, Bosch Professional levels are used.

Bosch levels are in demand when:

• creation of geodetic maps of high accuracy;
• installation of technical equipment and structures, for example, for the installation of power line poles;
• arrangement of the area;
• leveling of significant areas;
• predicting the parameters of subsidence of buildings and structures;
• internal construction and installation works (when laying floors and installing ceilings).

For domestic purposes, levels are often used when repairing residential premises. For this purpose, a separate type of measuring equipment has been developed, which is better known as a laser level. Such devices have the ability to project light rays onto flat surfaces, thereby perfectly marking corners. The use of a laser level provides maximum accuracy when laying tiles and wallpapering walls, that is, it helps in those places where it is necessary to comply with even geometric lines and angles.

Levels are useful for electricians too - with their help, you can accurately position the placement of switches, electrical outlets, as well as circuit breakers on the same line relative to the horizon or from floor level.

To understand the vast majority of users, it must be said that level and level are one and the same tool. Let's say more - even professional builders very often call the same device that way. Of course, there is no serious mistake in this, since both of these tools function according to similar principles and are aimed at solving approximately the same problems.

Nevertheless, there are fundamental differences in measuring instruments. So, a level is a device that can work with a single point of support, rotating around a circle. The action of the level applies only to two points, between which it is necessary to draw a horizontal line.

All levels of the Bosch brand are conventionally divided into categories according to two main criteria - the accuracy of measurements and the mechanism of action.

Depending on the accuracy of the measurements, there are 3 main types of measuring instruments:

• high-precision - the permissible error in measurements varies from 0.2 to 0.5 mm / m;
• accurate - the permissible error varies from 0.5 to 2 mm / m;
• technical ones allow the largest error - from 2 to 10 mm / m.

High-precision models include the Bosch BL 200 GC and Bosch GRL 250 HV Professional (0601061600) level, and the precise ones - Bosch Quigo + MM 2 (0603663520) and Bosch UniversalLevel 2 Basic (0603663800).

For typical terrain marking, determining relief differences, as well as binding to it, you can use the simplest measuring instruments with reduced accuracy characteristics. And here when measuring objects at all stages of repair and construction work, the most accurate data will be requiredthat can only be obtained using professional equipment.

Levels of the following types are distinguished depending on the mechanism of operation.

• Geometric - these devices emit a beam in a horizontal direction. Such a level allows you to measure the difference in the location of control points. They are fixed in the surveyed area with special slats. Geometric leveling, depending on the functionality of the equipment, can be simplified - in this case, it is performed from a single point, or complex, when the points are progressively changing.

• Trigonometric - these levels are often called "theodolites", they are needed to measure the elevation between the markings using a laser beam located obliquely. In this case, a ray is drawn between the level and the control point of measurement, the slope angle and distance are calculated, after which the required value is calculated using a special formula. The method is quite laborious, while on rough terrain it often gives an inaccurate result.

• Hydrostatic - such devices consist of a pair of communicating vessels filled with a special liquid. The reservoirs are connected by a hose or a hose. In the measured positions, by the difference between the parameters of the water column, it is possible to determine the size of the excess of one point over the second. This method is considered to be highly accurate, but the measurement distance is limited by the dimensions of the hose / hose.

• Optical-mechanical - thanks to such structures, it is possible to determine the parameters of control points using a light beam and a staff marked in a special way. Such levels have a pipe that allows visual observation, as well as devices for leveling the device in a strictly horizontal direction. To perform this type of calculation, users require professional skills and knowledge.

• Laser - these devices are considered to be the most accurate. The principle of their operation is based on the projection of a narrowly directed beam onto any investigated surface. Laser levels are quite easy to operate, they allow you to work not only with individual directions, but also with volumetric planes.

• Digital - these devices can be laser or optical. Their fundamental difference lies in the fact that they display all the information obtained in the course of measurements in a digital version and store them, and the most modern models even partially analyze them. Such devices make high-precision measurements, you can work with them without helpers, but at the same time they are very sensitive to mechanical damage, and the cost of such equipment is quite high.

The most popular among users are laser levels, represented by the models Quigo 2, PCL 10 Basic, PLL 2 EEU, GLL 2-15 Professional and other products of this series. Optical-mechanical (Bosch GOL 26D), as well as digital options (digital inclinometer GIM120 BOSCH, 0601076800) are in wide demand.

The most popular Bosch Professional levels include the following equipment.

• Combined laser levels (GCL2-50C, GCL2-50CG, GCL2-15G). Such equipment is highly accurate, ensures straightness of light beams and stability of nadirs. Optimal for construction and repair work of all categories. Thanks to self-leveling, the laser beams are leveled in just a few seconds.To set and move the level, one device is needed - it operates due to the location of the beams in the vertical and horizontal directions.

• Rotary levels (Bosch GRL 250 HV 0601061600, Bosch GRL 400 H Professional 0601061800, Bosch GRL 500 HV + LR 50 Professional) - this equipment is optimal for leveling surfaces of all types. It is powered by a rotating tower with laser light beams. This device is equipped with precision electronics that do all the work for the user. The only thing that is required of the user is just to put labels in control places.

• Level for checking floors (laser for checking the evenness of the floor Bosch GSL 2 Professional 0601064001) - such equipment is optimal for setting the screed or any other types of floors on a single level. The device allows you to record any change in the horizontal plane, while the beams of the measuring device start from the reference point and pass over the entire measured surface.

• Linear level (Bosch GCL 2-50 C 0.601.066. G00, Bosch GLL 2-10) - high-precision equipment for constructing measuring axes, forms a pair of vertical lines and a horizontal line. They are projected onto the ceiling and form a reference point, thus ensuring quick alignment across all major dimensions.

• Point (point laser Bosch GPL 3, Bosch GCL 25 0.601.066. B00, Bosch GCL 25 0.601.066. B03) - this device is equipped with a self-leveling option, has the ability to self-level. The projection is made from 5 points in 5 different directions. Optimal when carrying out work on moving corners in indoor spaces.

Let us dwell in more detail on the features of the most popular levels of the Bosch brand among users.

This includes the Bosch GCL 2-50 C 0.601.066 models. G02, Bosch GCL 2-50 C + Gedore Set 0.615.994.0KG and Bosch GCL 2-50 CG 0.601.066. H00). The principle of operation of such models does not differ in novelty - their analogues are also present in the lines of other manufacturers. Schematically, the operation of the device is reduced to the design of two laser surfaces, which are located perpendicularly towards each other along the control nadirs and zeniths.

The main advantages of devices with a Bosch combined laser are:

• the ability to project beams in a vertical and horizontal position;

The rules for working with levels are different depending on the principle of operation of the device.

So, when operating the optical-mechanical structures of Bosch, it should be borne in mind that its main element is a telescope with a magnification power of 25-35 times, it is placed on the tribrach, the length of which must be manually adjusted. The device includes a cylindrical level - it is necessary for horizontal alignment; in addition, there is an elevation screw in the design, which facilitates orientation in space.

Before starting work, place the measuring device on a tripod, then level it horizontally using the leveling screws. You can locate the desired location using the built-in bubble level. Next, the tube is aimed at the rail with the help of the sight, after which the required sharpness is set by moving the eyepiece ring.

The most accurate fixation on the built-in rail is carried out due to the focusing, as well as the directing screw mechanisms. All readings are taken and recorded. After that, you can start working with the second checkpoint.

Bosh laser levels allow you to set perfectly straight lines in several planes. Their principle of operation is based on focusing a stream of light, which looks like a bright point or a clear line of light (light is emitted by lenses and LEDs). The body is made of durable materials, a level is built inside, which allows you to set the beams horizontally.

It is very easy and simple to use such levels. To start measuring, the laser must be placed on a leveled horizontal support or tripod. With the help of a narrowly directed beam, a line or a point is fixed on the studied surface, which is necessary for calculations. When carrying out complex geodetic measurements in open areas, the rays are directed to the rails, and the displayed information is recorded.

Analyzing reviews of Bosch levels, left by users on a variety of thematic portals, it can be noted that the equipment of this brand is distinguished by functionality, practicality, high quality and durability.

The devices are equipped with high-capacity batteries - this makes the use of the equipment doubly convenient, since during measurements, users do not need to interrupt work to recharge the device.

Bosch equipment is highly accurate, but only at close range. With increasing range, the error increases - this is due to the scattering of the light beam. Users pay attention to the fact that in bright light and in the sun, the laser beam of Bosch levels is almost invisible, and this significantly reduces the accuracy of measurements.Levels of this brand are lightweight, compact and ergonomic, so the equipment can be easily moved from place to place.

In general, users highlight the following advantages of this brand's products:

• compactness;
• light weight
• mobility;
• affordability;
• practicality.

Of the minuses, you can note:

• insufficient data accuracy when measuring at long distances;
• light beam scattering;
• individual components of the kit have to be purchased additionally, since they are not included in the basic kit.
