What are the specifications and models of levels?

The specifications and models of the level are determined by the following: Accuracy level: Indicates the maximum allowable error of measurement. The higher the accuracy, the better. Observation distance: The maximum distance of the leveling rod for clear observation of the level. Magnification type: The ratio between the eyepiece observation level ruler image and the actual ratio. Model: Models with different parameter combinations from different manufacturers. For example, Leica Nivel 26 indicates an accuracy of 2mm and an observation distance of 60m.

Level specifications and models

The specifications and models of the level are mainly determined by the following parameters:

• Accuracy level: Indicates the maximum allowable difference between the average value at the minimum reading of the instrument and the actual height difference. The higher the accuracy level, the more accurate the level measurement. Common accuracy levels are: 0.5mm, 1mm, 1.5mm, 2mm, 3mm.
• Observation distance: Refers to the maximum distance at which the level eyepiece crosshair can clearly observe the scale on the level ruler. Common observation distances are: 30m, 50m, 60m, 80m, 100m.
• Magnification type: refers to the ratio of the level ruler image observed through the instrument’s eyepiece to the actual level ruler image. The larger the magnification, the finer the level gauge's reading. Common amplification types are: 20x, 25x, 30x, and 40x.
• Model: Levels from different manufacturers will have different models based on their accuracy level, observation distance, amplification and other parameters. For example: Leica Nivel 26, Sokkia 486, Zhongrui ZDL-2, Topcon AT-G3.

The meaning of the specific model

Taking the Leica Nivel 26 level as an example, the model is represented as follows:

• Nivel: means Leica's range of levels.
• 2: Indicates the accuracy level is 2mm.
• 6: Indicates that the observation distance is 60m.

Based on the above parameters, users can choose the appropriate model of level according to their actual measurement needs.
