Our flagship seismometers are KU-3D and KU-1D which measure in 3D and 1D, respectively. The KU-3D and KU-1D both fulfill DIN 45669-1 requirements. Their high sensitivity allows applications in mining, geothermal plants, salt caverns, oil & gas, deep thermal energy storage, CCS, as well as construction according to DIN 4150. These seismometers contain SM-6 coils which are used in well-established seismic sensors all over the world.
