Force-balance broadband seismometer CME-6011

The three-component force-balance broadband seismometer CME-6011 is very rugged and easy to operate. 

To start working with it, explorers just need to install the seismometer on a flat surface, turn it on and wait for a few minutes till the sensors settle down. The stability and high linearity are guaranteed by the force-balance feedback. 

CME-6011 is a high precision broadband seismometer featuring a low self-noise level. We have a considerable experience of adapting this model to field-oriented applications.

The CME-6011 frequency characteristic with the poles and zeros presentation is available at the link on the website of Incorporated Research Institutions for Seismology (IRIS).
