IMU-3C is a three-components intelligent monitoring unit, which can carry out three-channel data acquisition. Based on the Mobile communication system, WIFI, Ethernet and other data transmission interfaces, IMU-3C is able to fulfil remote parameter configuration, real-time data transmission, real-time data monitoring and real-time data quality evaluation, etc. Equipped with external sensor connector that compatible with multi-types of sensors. Equipped with external power supply connector that customized for long term data acquisition. Integrate with GNSS module and internal antenna, external GNSS antenna is optional also. A surface wave processing software which developed by DTCC is now available for real-time dispersion, surface wave velocity analysis, inversion and imagining. 16 ports charging case The case is used to recharge at most 16 IMU-3C per batch. 4A charging current, fast charging.
