Key Specifications/Special Features:
IGU-BD3C-5 is a low-cost, broadband, and micro power consumption broadband smart seismic sensor. Based on the high-sensitivity geophone DT-SOLO--proudly produced by DTCC, and incorporated with electronics and software technologies in mobile internet era. With internationally well-received and reliable electronic spread spectrum technology, the frequency band range of IGU-BD3C-5 is up to 0.2Hz-150Hz. Due to its high reliability and high level of customization of storage and power capacity, it is very suitable not only for traditional active seismic exploration, but also for long-period observation of natural microseismic, transient surface wave survey and mobile station natural earthquake monitoring, etc.
