Large Depth Dual Frequency Induced Polarization Instrument
The Large Depth Dual Frequency Induced Polarization Instrument is a frequency-domain geophysical tool. Its transmitter delivers 1000 volts and 20 amperes of power. The system transmits and receives two low-frequency step wave signals simultaneously. It operates across three defined frequency groups, including 1Hz/1/13Hz and 4Hz/4/13Hz pairs. An integrated GPS provides precise survey coordinates. Internal digital chopper decoupling circuitry minimizes natural ground current interference. The unit is built for field portability while maintaining a high signal-to-noise ratio for clear data.
Construction involves ruggedized cases for the core transmitter and receiver units. These protect the electronics during transport over rough terrain. The system uses heavy-duty cables and corrosion-resistant electrode connectors. Its design allows for extended operation with standard field batteries. The interface provides real-time readouts of apparent resistivity and chargeability parameters. This setup enables on-site preliminary data assessment by the survey team.
The Large Depth Dual Frequency Induced Polarization Instrument is used for deep mineral exploration. It maps sulfide ore bodies like copper and zinc at considerable depths. Hydrogeologists apply it to find deep groundwater resources in arid regions. Engineering projects use it to assess bedrock integrity for large infrastructure foundations. Teams deploy it in linear surveys, inserting metal electrodes into the ground. The instrument calculates subsurface polarization effects to identify geological targets.
Tactical Supply Pakistan sources this instrument for survey teams needing robust deep-prospecting data. Clients receive a system validated for performance in Pakistan’s diverse geological environments.
Why are specific low frequencies like 1/13Hz used in this instrument’s frequency groups?
These very low frequencies provide greater depth penetration for the electrical signal. They allow the measurement of slower polarization effects in deep geological formations. This is essential for detecting targets located several hundred meters underground.
