Seismometer CME-4211

CME-4211 is 3-component broadband seismometer well suited for rapid deployment in arrays, monitoring of structures, and for permanent installation in locations with the background noise higher than the New Low Noise Model. 

This easy-to-install, very rugged instrument does not require any maintenance, mass locking and centering. This model is ideal for portable applications, demanding the combination of high performance, low power consumption, compact size and low-cost. 

1-component (vertical or horizontal) version of the 4211 model is available.
