About leveling devices
Leveling devices are measuring instruments for determining height differences and angles. Leveling devices measure more accurately than spirit levels and are particularly suitable for measuring longer distances. For more information on features, applications, and different versions, please refer to our guide.

What was leveling?
Leveling devices are part of the measurement technology and are used to measure height differences and angles. Depending on the configuration of the optical levels, distance measurements are also possible.
Classic leveling consists of a telescope whose optics are equipped with cross-hairs, the so-called cross-line plate. Looking back and looking forward at a measuring plate, the difference in height between the locations of the measuring plate is determined.
Most of the levels have two short horizontal lines above or below the horizontal line of the target cross in the optics next to the cross line to target the target point. With this method, distances can be determined using the classical measuring plate by reading and then calculating with a formula.
In addition to measuring plates, separate markings (for example the so-called meter line) are used at the points to be measured to measure differences in height and, for example, to define slopes for the application of slope screeds. Similarly, very exact angle measurements can be made with the horizon circles on the device.
For use, the instrument is mounted vertically on a tripod. For adjustment, the device itself has aids such as spirit levels attached.
Leveling devices are characterized by a very high accuracy, which far exceeds the possibilities of a water wagon, for example – assuming proper use.
In addition to the classic optical leveling system, a wide range of laser-based measuring devices has become established, offering more possibilities in terms of detectable sizes and ranges.
A digital leveling system is self-leveling, reading and registering – technically a combination of leveling and digital camera. The target beam is separated in infrared and visible light in a partial cube. The infrared light reaches the CCD chip and the visible light reaches the viewer unhindered. The measurement plate is comparable to a barcode whose image is compared with one of the images stored in the device. If the match is made, the stored value is output digitally, appears on the display and is available for a digital evaluation.
Laser-based leveling devices are very accurate and comparatively easy to handle.
Areas of application of leveling devices
Leveling devices are used in measurement technology to measure height differences and angles. From this, horizontal surfaces or defined slopes can be produced as well as structures (foundations) or machines can be set up. Leveling devices are required for dry construction, floor construction and stair construction as well as for carpentry work and for gas and water installation. Leveling is also an indispensable tool for building acceptance, the recording of inventory data on areas and buildings, quality controls as well as drilling and demolition work.
What levels are available at Conrad?
In our online shop, various leveling devices are available, some of which are designed for specific measuring tasks and which sometimes combine several measuring options. You can select leveling devices with us according to the following aspects:
Category
The device category describes the application area or the measurement technology (optical/laser). Here you can also find a smartphone application with the corresponding app. So-called tile lasers are used for the exact laying of tiles and laminate. Some laser devices have been specially developed for working at high ambient brightness.
Calibrated to
- ISO: The product is tested according to DIN EN ISO 9001:2015.
- Factory default: Tested with a calibrated sample device.
Optical magnification
The optical magnification of the devices with optical equipment reaches values from 20fach to 32fach.
Range
This device-specific value covers the values from 5 to 800 meters.
Key features
Here you can find leveling devices including laser receivers, including bag and/or stand and self-leveling products.
What should you pay attention to when buying leveling units?
First familiarize yourself with the tasks to be solved in order to find a suitable leveling system. High-quality devices are price-intensive.
The first priority should be the precision of the device. In the case of classical (optical) leveling, the accuracy is given in millimeters of deviation per measured kilometer. For top-of-the-range devices, this value is approximately 2 to 10 millimeters.
Since most of the leveling work takes place outdoors, pay attention to the existing protection class (IP) to avoid damage to the device and influences of the measurement result due to weather influences.
Our practical tip: Angle value Gon
The Gon is often used as an angle value in measurement technology. The full circle has 400 Gon in this unit of measurement. The conversion factor is 1 Gon equal to 0.9 degrees. A degree is equal to 1.111 (period) Gon. The right angle of 90 degrees has a value of 100 Gon with this unit of measurement.
Safety instructions when handling leveling devices
When working with any type of surveying plate in the immediate vicinity of electrical equipment such as overhead lines or the proximity of railway equipment with electrical operation, there may be a risk of a fatal electric shock. Keep a safe distance from such equipment. It may be necessary to inform the competent authorities before the start of the work.
Surveying in the event of lightning storms poses the risk of lightning strikes. Do not carry out any surveying work during thunderstorms!
Never look into the sun with an optical leveling device and also do not look into the laser beam of electronic leveling.
Inadequate protection or a poorly recognizable marking of the measuring location can lead to dangerous situations in road traffic, on construction sites or in industrial and commercial plants. Comply with the statutory accident prevention regulations and road traffic regulations.
