Low Frequency 1Hz Land Case Geophone

Low frequency 1hz high sensitivity geophones 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-1A geophone, with Max.coil excursion p-p 6.0mm.

● 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 600.0V/m/s.

● Different type of geophone cases which are suitable for land,desert, snow, marsh and transition zone respectively.

● Widely used in passive seismic survey and earthquake monitoring system.
