About the Lennartz electronic LE-3Dlite MkIII
The LE-3Dlite MkIII contains three orthogonal sensors electronically extended to a 1 Hz eigenfrequency, giving a flat response at frequencies well below those of standard exploration geophones. That makes it a standard sensor for horizontal-to-vertical spectral ratio (HVSR) measurements, microzonation and site-response studies.
It is also used for structural and construction vibration monitoring and in temporary seismological deployments, connected to a separate digitiser or seismic recorder.
