SmartSolo IGU-BD3C-5


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 SmartSolo Inc, and incorporated with electronicsand 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.

High-quality seismic data derives from high-quality seismic sensors. DT-SOLO is a high-sensitivity geophone specially designed for point receiver applications. It is well-known in the seismic industry as the top-quality high-sensitivity geophone which is widely used by contractors and equipment manufacturers.
