High sensitivity geophone 3Hz(P/N: ST-3) in vertical direction (P wave) and horizontal direction (S wave) are available, which are suitable for deep seismic exploration, engineering pulse measurement and other vibration analysis.
● Long travel version of the ST-3 geophone.
●Special orientations upon request beyond the normal vertical and horizontal options.
● Widely used in industrial vibration-monitoring systems.
● Rugged construction with precious-metal, rotating-coil contacts.
● High sensitivity of 200.0V/m/s.
●1-year limited warranty on basic element exclusive of high voltage, lightening or physical abuse.
