AT-100
Broadband Current Source
Description:
AT-100 is lightweight, compact and portable broadband geophysical current source with wide range of the output frequencies and currents, allowing large variations of the load impedances.
Current Source Applications:
- Near-Surface & Mid-Range Investigations
- Mining, kimberlites (diamonds) and groundwater exploration
- Geological, landslide, faults, melt rock, aquifer and karst mapping
- Geological engineering, pipeline condition analysis, land reclamation, environmental studies
- Geodynamic, archaeological, dike and sills, ecological investigations
- Geological, volcano and earthquake monitoring
- Permafrost & glacier research
Main Features:
- All-in-One System – Time and Frequency Domain ground EM data acquisition
- Stand-Alone System – no external devices (PC, tablets, etc.) needed to carry out field DAQ
- Field Survey Capabilities: EP, VES, DES, Electrotomography, Misse-a-la-masse, TDIP, FDIP (Amplitude & Phase), SIP, CSAMT, CSMT, VLF, FDEMS, IEP, TDEM
- Stabilized output current up to 1A for driving inductive loads or grounded dipoles
- Broadband output – 50kHz to 0.01Hz
- Intuitive Hi-Res color touchscreen GUI
- Real-time parameters monitoring and notifications
- GPS and cable synchronization options
- Manual and Automatic operation modes
- Powered by 12V external battery
- Portable, lightweight
