3DLG-2

3D land geophone (2Hz)

The 3D Land Geophone 3DLG-2 is the ideal accessory to add to your seismic instrumentation and perform HVSR, MASW and Vibration Analysis. One vertical and two horizontal high-performing sensors, with 2Hz resonance frequency and properly coupled, are mounted in a robust waterproof case, delivered with adjustable feet and inter-changeable rods. 3DLG-2 has a connector that blocks the sensor elements to avoid damage during handling. The system is supplied complete with connecting cable for the seismograph and a carrying case.
