SM24 Geophone 10Hz , High Precision Geophone
The high-precision geophone has advanced design, high false frequency and excellent anti-interference. The tolerance of each parameter is controlled within ±2.5%, the distortion is less than ≤0.1%, the performance is stable, the accuracy is high, and the signal is high. The collection is rich and accurate, and is suitable for all kinds of accurate seismic exploration. All parts are processed by precision machining, and the production process is mature and stable.
The SM-24 Geophone 10Hz is mainly used for geological seismic exploration of oil and gas fields, coal fields and geo-minerals in land, lakes and other areas with land depth and water depth of not more than 3 meters.
