The Ermenrich PL30 Optical Level is an instrument that can measure the vertical level (height difference) between two points at a distance from each other, angles in the horizontal plane, and the distance to an object. The magnification is 32x, which enables you to see the millimeter scale of a leveling rod at a distance of up to about 50 meters (160ft). The “E” metric graduations will be visible

The Ermenrich PL40 Optical Level is designed for taking measurements on the ground: height differences, angles, and distances. Its design uses a pendulum compensator with a magnetic damper to reduce vibrations more effectively than similar devices that use an air damper. Therefore, the Ermenrich PL40 level is well-suited for use on construction sites around heavy machinery that create strong vibra
