High sensitivity!!Advanced Technology HF-MPI Mine Locator Natural Electric Auto Frequency Selector

Specifications

HF-MPI  Mine Locator Natural Electric Auto Frequency Selector  

Compare with traditional electric prospecting instrument:

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.

Main functions and features
1. Automatic noise reduction; super anti-jamming.
2. 3 frequencies or 30 frequencies measuring at one time.

3. Operating functions are all on the LDC screen, easy operation.
4. Auto-measuring, auto-stocked data. It doesn’t need to record the measured data and the data won't be lost when power off.
5. It can storage 20 curve measuring data of3 frequency and 30 frequency.
6. Curve and data are displayed on LCD screen. Curve and data also can print by micro printer or PC printer.
7. Power supply rechargeable battery.
8. Electrode test and power monitor
9. Whole weight.2KG, size: 24CM×13CM×16CM
