    How to Use a Laser Level?
    The laser level is widely used in the construction industry, is a measuring machine for measuring the level. It has the advantages of high accuracy, convenient use, fast and reliable, and can be used in surveying, large-area site surveying, floor level marking, settlement observation, etc. will explain in detail the operation and control steps of the laser level for wholesale online. 1. Open the tripod, keep its height near the chest, keep the head of the frame roughly level, step on the toes into the soil, and then use the connecting screw to connect the equipment to the tripod. 2. First of all, we must understand the names and functions of the parts of the laser level and be familiar with their use. The laser line meter is made by fixing a laser device on the tube of an ordinary level telescope. The laser device consists of a nitrogen-neon laser and a prism light guide system.Best price laser levels for sale

    Working Principle of Levels
    A level is a measuring tool that establishes a horizontal line of sight to determine the height difference between two points on the ground. Its main components include the telescope, tube level (or compensator), vertical axis, base, foot screw. According to the structure, the level is divided into micro-tilt level, automatic compensated level, laser level and digital level (also known as electronic level). According to accuracy, it can be divided into precision level and ordinary level. Automatic compensated instrument Automatic compensated level is a level that obtains horizontal sight line by means of automatic compensator.
    How to Calibrate Laser Level?
    The best laser level should meet the following conditions The level axis of the vial should be parallel to the collimation axis of the telescope's collimator. (Main condition) The collimation axis of the telescope does not change position due to focusing. (Main condition) The circular level axis should be parallel to the rotation axis of the rotary laser level. (Minor condition) The horizontal wire of the crosshair should be perpendicular to the rotation axis of the laser level. (Secondary condition) Inspection before calibration The principle of inspection and calibration sequence: The previous inspection items are not affected by the following inspection items. Inspection method: The leveling axis of the level should be tested and calibrated equally with the rotating axis.
    FAQ - Laser Level
    What’s the rotary laser level working principle? The working principle of laser level is to use the monochromaticity and coherence of laser. A glass or metal sheet with a certain shading pattern can be assembled in front of the telescope objective lens, that is, the zone plate, so that the diffraction interference generated by it can be made. After focusing by the telescope, within the focusing range of the zone plate, a bright and fine cross-shaped or circular laser spot can be obtained, so that the target can be aimed more accurately. If the front and rear leveling rulers are equipped with photoelectric receiving targets that can be tracked automatically, leveling can be performed. In the construction survey and the assembly of large components, a laser level is often used to establish a level surface or a level line.
