The spirit level (popularly known as leveler) is a measuring instrument used to place the axis in a vertical or horizontal position. High precision even with temperature oscillations. Very good readability and longevity. Two levels of leveling. One level for horizontal measurement, level for vertical measurement and level for measuring angle of 45 degrees. The levels are made of acrylic unbreakable glass. At the end of the aluminum case, there are plastic caps that protect it from impact. Measuring accuracy up to 5 mm / m. Horizontal measurement, vertical measurement. Measurement at 45 °. Accuracy ≤0.5 mm / M.
