Seismometer CME-3311

The seismometer is characterized by a wide dynamic range, low self-noise, high gain, low power consumption. It is very reliable and has no moving parts to be broken or wear out.
Like other molecular-electronic seismometers, this model does not require mass centering for installation and mass locking for transportation. The seismometer is well-suited for portable and permanent installations in locations with the background noise close to the Low Noise Model. It can be used in exploration seismology, engineering geophysics, structural health monitoring and many other applications. 3-component and 1-component versions are available.
