B20 Optical Level


The B20 compensator uses a magnetic damping system, minimizing vibrations from the surrounding environment and ensuring stable sightlines; its ultra-short sight distance of 20cm offers great convenience in narrow spaces. The IPX6 high protection rating withstands strong splashes from any direction, making it suitable for harsh outdoor environments.
