Horizontal geophone PS-2B

verticalindustrialhigh-sensitivity

Product overview
The PS-2B geophone is a low-frequency, low-sensitivity passive geophone equipped with a rotating coil system to suppress lateral shock forces. Available in P-wave and S-wave configurations, it supports single-component and three-component measurements and is suitable for geophysical exploration, engineering vibration monitoring, and handheld instrumentation.
