Electrical Resistivity VIP Geophysical Land Products

The VIP series of Electrical transmitters are purposely designed for deep Induced Polarisation or Resistivity sounding investigations. Predominantly used as part of mineral exploration studies the VIP series includes four systems with different power specifications.

VIP 3000 Resistivity and IP transmitter.

To simplify operation the instrument manages the injection current and voltage automatically. Prior to injection the VIP will check to make sure suitable power is available. In addition this feature stops the instrument from being misused. VIP systems can be controlled via a remote PC or laptop to help configure and trigger the system at great distances. All VIP systems offer four operating modes;

Time domain waveform, on Time (Ton) and Off time (Toff),
Frequency domain waveform, outputting two user selectable frequencies from 0.0625Hz and 4Hz.
Dual frequency mode, a base frequency is selected from 0.0625 and 0.5Hz and the high frequency is fixed at 8 times the base frequency.
Continuous mode, injects a constant DC current into the ground.

Four VIP systems are available; VIP3000, VIP4000, VIP5000 & VIP10000- which makes the range suitable for use in almost all geological formations.

In situations where a wired synchronisation is not possible the VIP can be operated alongside the IFullwaver for accurate absolute time stamps when recording precise full waveform time domain measurements. See datasheets for individual specifications.
