EM-IP Tx Controller
Instrumentation GDD have recently launched the production of its EM-IP Tx Controller, a compact, robust and easy to use instrument designed for obtaining optimized results of EM and IP surveys.
This instrument enables GPS synchronization of your GDD receivers with any of your transmitters for both electromagnetic (EM) and resistivity/induced polarization (IP) surveys. It measures and records the GPS timestamp current.
- √ Accurate apparent resistivity calculation
- √ Advanced signal processing for EM surveys (excellent conductors (ON-TIME))
- √ Infinite electrode and remote station current monitoring
- √ And more...
Features
- Useful for EM and IP surveys
- Records GPS timestamp current full waveform
- Easy to operate and inexpensive
- Shock resistant, portable and environmentally sealed
- Transfers data to PC with USB Memory stick
- USB Firmware upgradable
- Offset cancellation
- Accessories: socket plugs (rated 50A), external GPS antenna, memory stick, Master-Slave IP cable and/or NordicEM24 synchronization cable.
- Applications : mining exploration, groundwater exploration, geotechnical investigations and other related fields
