Accudata GVM-2 Seismograph
The Accudata GVM-2 – our most powerful seismograph.
The GVM-2 is designed to measure ground-borne vibration and air over-pressure during quarry blasting or explosive demolition. It is also an ideal instrument for monitoring during civil engineering works such as piling. It is easy to use and is available for hire or sale.
Packed with features, the Accudata GVM-2 is a very powerful seismograph. As well as having a bargraph mode and a trigger mode, the GVM-2 also has a combined mode which allows continuous monitoring in bargraph mode and at the same time also a (user defined) trigger, such that when a user set level of vibration is exceeded, a tri-axial waveform event is recorded for a number of (user-defined) seconds.
