Most portable underground water detector
1,used in minerals and water prospecting
2,small cubage&light weight, carry about
Most portable underground water detector ,HF-MPI Model
Compare with traditional electric prospecting instrument:
traditional electric prospecting instrument | Natural Electric Auto Frequency Selector |
Need manual supply power, heavy equipment and complicated wiring. | Do not need power supply, use natural electric field, through special amplify method it just need 20 meters receiver pole to complete survey. |
Need 3-5 people or more than 10 people to operate the equipment with heavy work and low efficiency. | 2 people is enough to finish the work with high efficiency |
Heavy weight about 50-500KG, hard to remove. | Light weight less than 5KG, easy to bring. |
Need to convey the data to PC and use different kinds of software to draft and analyze. | Printing all kinds of curve immediately with the portable printer and analyzing at the same time. You can adjust and change survey dispose. |
Main application
Use natural electric field and resistivity parameter produced by different of the geologic structure. It is widely using in prospecting metal minerals, non-metal minerals, underground water prospecting etc. Working area is from large to several square kilometer to small to several square, especially for mountain area and city prospecting.
Only one person will finish indoor and outdoor work
Do not need manual power supply,small cubage,light weight,carry about,high efficiency and exact address. It get over the default that traditional equipments have such as need many people to work together, heavy weight, complicated operation, low working efficiency and long lines.
Press one button to finish all the survey operations
Machine is automatic control by micro PC. Easy operation. A press one button to finish all the operation. It does not need especial knowledge. When the survey is finished, press the button to display the curve and you can analyze at the same time.
High anti-jamming capability
You can get the good curve in the noise road and high electric jamming area for signal via frequency selector and digital processing.
Get survey parameter through Multiple-frequency, Multi-aspect and multi-measurement.
It can survey in different position, do fixed point survey, solve same special geophysical problem and gather multi-measurement parameter through different kinds of survey method.
Widely application and flexible using
using for locator underground water, minerals and solve engineering geophysical problem and geophysical disaster. Working area is from large to several square kilometer to small to several square, especially for mountain area and city prospecting.
