LE-3D/5s MkIII

LE-3D/5s MkIII

The LE-3D/5s seismometer is perfectly suited for all kinds of local and regional seismic monitoring, H/V measurements and seismic microzonation. The seismometer is made for fieldwork in harsh environment: very robust and ultra-low power consumption. Until present, we have manufactured more than 1000 instruments of this type.
