2Hz High Sensitivity Geophone(P/N: ST-2A) is designed for receiving deep, low frequency and weak signals. With the characteristics of ultra-low natural frequency, ultra-high sensitivity along small volume and lightweight. ST-2A is suitable for engineering vibration measurement and single point signal acquisition with vertical, horizontal or three-component combination optional. High signal-to-noise ratio and wide dynamic range … Continue reading 2Hz High Sensitivity Geophone
