Broadband Seismometer

Model KS-2000 and KS-2000M

2*1000 V/(m/sec) sensitivity (other sensitivities on special order)
Three-component
120 s to 50 Hz

The Geotech Model KS-2000 is a new broadband seismometer based on the time proven Model KS-54000. Its small dimensions make it ideal for portable applications. However, both a surface package and a borehole package are be available. A short-period version KS-2000SP, and a school version KS-2000EDU/20s are also available. Its manual can be downloaded by pressing here (2.8MB). The motorized version KS-2000M performes mass centering on remote command, and this feature is standard in the borehole version KS-2000BH.
