Technical data Manufacturer: Pro Manufacturer code: 3-01-01-BE-080 Length: 80cm Painted spirit level horizontal and plumb indicator 800 series 80cm PRO800 series spirit levels are equipped with vials with a specially designed oval shape, enabling easy reading, the so-called ERS (easy reading system). Thanks to this solution, the angle at which the measurement is taken becomes completely irrelevant. The vial has no sharp edges at which light would refract. Additionally, it features a magnifying glass effect, allowing the image of the bubble to be enlarged by 30%, , which also becomes much clearer The vial for determining the level has been designed to allow the level to be measured in two positions – normal and reverse – while maintaining measurement accuracy. This feature is particularly useful when measuring the level of ceilings or beams at height, when reading the vial from above is impossible. The vial accuracy is 0.5 mm/m = 0.029°. The new vial, made of high-quality acrylic glass with a semicircular shape, is additionally very well illuminated, making work easier in poor lighting conditions. It uses a modern (smooth and rounded) vial mount. The edges do not accumulate any dirt, which eliminates the problems associated with cleaning the spirit levels from adhesive or mortar residue. ** Illustrative photos
