BV-4 ( Blastiong Vibration 4 ) type blasting vibrometer Key words: blasting vibrometer, blasting vibration monitor, blasting vibration recorder Promotion support: free home delivery, product warranty for two years                End customers support cash on delivery. Bonus blasting project management requirements ( GA991-2012 ) Main machine waterproof, shockproof, anti-shock box BV-4 type blasting vibrometer is a new type of blasting vibrometer, which is mainly used to record and analyze the vibration signal generated by blasting. The blasting vibrometer has high integration degree, large storage capacity, wide frequency band coverage, good signal quality, and strong software analysis and processing capability. Widely used in highways, railways, bridges, dams, buildings, tunnels, quarries, mines, directional demolition and other engineering sites with blasting needs. At the same time, it has also been used by domestic universities, research institutes and supervisors for scientific research teaching and blasting environmental supervision and evaluation.
