Seismometer CME-6111

The CME-6111 seismometers combine the low-noise molecular-electronic sensing element (transducer) and the electrodynamic feedback which results in a very flat response over a wide frequency range, high dynamic range and greatly improved time and temperature stability of the instrument parameters. 

Like other molecular-electronic instruments, the 6111 seismometer is very rugged and does not require any special means or procedures for transportation and installation. The only procedure to start its operation is to place the seismometer on a rigid horizontal surface, turn it on and wait for several minutes. The seismometer can be used in various areas including permanent stations and field surveys.
