10 best optical levels

Optical level - a tool for determining the difference in height between reference points of controlled objects. The principle of operation is based on the calculation of the difference of measurements from the main (basic) reference platform and the reference mark on the object. For geodetic works applied rake with a scale. In the telescope, the data is removed from the divisions applied to the glass. Measurement accuracy is enhanced by a magnifying optical system in the range of 20 ~ 32 times. The error rate is measured in millimeters, correlated with a distance of one kilometer.

• There is no verification.

ADA BASIC - an inexpensive level for its characteristics

The tool, made according to the classical scheme. Equipped with an optical tube with enlightened optics. The exhibition on the horizon through an automatic compensator. Rough orientation - bubble level.

The device is designed for use in the field. The accuracy of the parameters is ensured by the stability of the base. The level is used to perform the main shooting, including industrial and civil construction.

Pros:

• Great price for a device of this level.
• All-weather application.
• Great review.

Minuses:

• There is no verification, you need to buy separately.
• The package does not include a tripod.

RedVerg RD-GAL20 - a device for everyday use

Universal optical instrument for the production of operations at the construction site or in the field, for geodetic works. It is applied at installation of metal industrial designs, road construction.

Image clarity, wide angle of view provides an enlarged diameter of the lens. The picture is reproduced in the live image. The exhibition on the horizontal and vertical plane provides an automatic compensator with a magnetic damping mechanism.

Pros:

• Good picture quality.
• Convenience of use and settings of optics under own eye.
• Unpretentious in construction and in the field.

Minuses:

• Poor equipment for such a price.
• Low magnification with larger lens input diameter.

RGK C-20 - good optics for the price level

Easy to use, with clear and easy to read scales, optical device. It features a high quality optics, which allows you to confidently distinguish between distant objects and fixed points.

Direct reproduction of a picture that is distinguished by high-definition images is used. Optics provide a wide angle of view, which is convenient for finding remote small parts. The exhibition on the horizon is made continuously adjustable with three screws with precision thread.

Pros:

• Reliable, easy to use level.
• High quality optical system.
• Smooth adjustment.

Minuses:

• Insufficient increase.
• The package does not include a rail and a tripod.

GEOBOX N7-26 - a level with fine protection

The model of an optical level is designed and intended for work in difficult conditions of production and field work. It is provided with a robust housing made of high-quality metal and a system of protection against dust, dirt and water.

The image quality of the image, the clarity and contrast of small parts are due to the optical system with increased magnification and low loss of luminous flux.

Pros:

• Resistant to drops from low heights and vibrations.
• Works great in rain and sleet.
• Passed verification and certification.

Minuses:

• Rake and tripod for a fee.
• Light and brand surface.

CONDTROL 32X - small measurement error

High-precision with a large diameter lens and optical zoom level. It is used for an extended list of works, - industrial and civil construction, the construction of critical metal structures, road markings, geodetic works.

Accuracy of readings is provided by a search sight, an exhibition system by bubble level with subsequent correction by an automatic compensator.

Pros:

• Small deviation from the original readings, good measurement error.
• Passed verification and certification.
• A good ratio of increase and luminosity.

Minuses:

• The compensator is sensitive to external sources of vibration, for example, the grid oscillates from a passing train.
• Homely grade, everything has to buy more.

BOSCH GOL 26D - complete set for work

Measuring device of excellent workmanship. Equipped with excellent German optics. The diameter and magnification give an excellent picture of the image in normal and cloudy weather.

Provides a smooth manual adjustment of the focus under the physiological characteristics of the individual. Built-in protective mechanism for fixing the compensator during transportation of the level.

Pros:

• Excellent clarified optics, high-quality image.
• Excellent measurement accuracy at the construction site.
• Build quality, complete set to get started.

Minuses:

• Delivered without case.
• A tall price, but justified by the capabilities of the device.

IPZ H-05 - the best in accuracy

One of the best optical levels of measurement error. It is used for operations of 1 and 2 accuracy class.It is intended for work on the state order, test sites, geodesic surveys with high requirements to the quality of indicators.
