Pioneers, Innovators and Experts

HBK was formed in 2019 by the merger of two market-leading organizations: HBM and Brüel & Kjær. Both companies have a long history of providing innovative and high-quality solutions in test and measurement technology for various industries.

However, our journey is a continuous one and the ever-growing HBK constellation reflects our commitment to innovation, the latest technology and new opportunities as we untap the potential of combined knowledge and insight within three physical domains – mechanical, sound and vibration and electrical.
