SM-24 Equivalent Geophone Sensor
SM-24 equivalent geophone Sensor (ST-10PN) is designed to offer the highest performance in seismic exploration, which is equivalent to SM-24 geophone. Low distortion, combined with excellent specifications, provide high-fidelity data in 2-D and 3-D surveys. The extended bandwidth allows the full potential of 2-ms/24-bit systems to be realized.
● Tight specification, low-distortion geophone.
● Extended spurious over 240Hz, allowng full bandwidth at 2-ms sampling.
●Backwards compatible with SM-24 equivalent geophone element.
● For 2-D & 3-D seismic exploration with bandwidth from 10Hz up to 240Hz.
●1-year limited warranty on baic element exclusive of high voltage, lightening or physical abuse.
