High sensitivity geophone 2Hz(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 with small volume and light weight. 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.
● Low natural frequency of 2Hz.
● Ultra-high sensitivity of 260V/m/s.
● Low distortion≤0.3%.
● Single point acquisition, light weight and portable deployment.
●For single geophone string: Equipped with Universal aerospace connector for connecting with main stream acquisition systems.
● For single geophone string: Equipped with stainless steel case with compact and high strength structure.
● For single geophone string: Specialized steel rope for portable hand harrying is available.
● For single geophone string: Equipped with specialized short circuit connector, to ensure service life of the geophone.
●1-year limited warranty on basic element exclusive of high voltage, lightening or physical abuse.
