Description
Simple
introduction
NEF**0 Natural VLF Prospector is the
other upgrade product based on continuous improvement and
enhancement. The applied module of full imported IC control and
filtration completely reaches international leading level to fixed
machine filtering of frequency; you can get perfect stability and
accuracy in data measurement. It is also further improved in shielding
interference signal and design of anti-jamming.
NEF**0 is more convenient as it realizes
PC communication in latter data processing. It has many advantages
like simple operation, easy to carry, stable data, strong
anti-jamming ability, high accuracy, fast speed etc. Comparing to
traditional electrical prospecting equipment, it is *0 times more
quick while the weight is *0 times less, which saves large amount
of time, manpower and materials for field survey. It is your
optimal assistant in geophysical survey.
Main principle
NEF**0 Natural VLF Prospector uses
relative parameters like resistivity variation produced by natural
electric field and different geologic substance to determine the
geological abnormity we are seeking. Through the relative physical
parameters variation like different conductivity between ore and
non-ore object, it can get the relative information as ore vein
direction, buried depth, thickness and deposit etc. In more than *0
years' practice, we gained outstanding achievement and customers'
common praise.
Application:
1.
Widely used in metal ore prospecting, non-metal ore's detailed and
general survey to decrease the venture of mineral investment and
improve exploration success rate and
scientificalness.
2.
Applied in underground water detect to meet the demand of drinking
water, industrial usage and agricultural
irrigation.
3. Also
used in engineering geological prospecting, disaster geological
detect, coal goaf, archaeological mining, city exploration,
non-metal pipe survey as well.
Main features
1.
Fast and high efficiency:
Complete
about ***0m profile measurement in one day to realize geological
abnormality in different depth, the prospecting speed and
efficiency is improved about *0 times more than traditional
resistivity method.
2. Easy
to carry:
Without
heavy power supply, it uses low frequency signals in earth natural
electric field as signal source, and the complete set weight is
less than 5kg so easy to carry.
3. Easy
operation:
Equipment is automatically controlled by micro
PC. You can learn its operation in *0 minutes. It will take 2h for
persons without prospecting experience to finish
training.
4. Good
precision and high accuracy:
Apply
imported control module and filtering IC chip to do measurement,
the data is high stable and accuracy, the resolution is up to
0.**1mV, precision is±1%, and fixed error of frequency is
1%.
5.
Strong anti-jamming capability:
It has
advanced anti-jamming technology and multiple anti-jamming designs.
You can observe abnormity curves result with good repetition even
in weak signal area, city, high electric jamming area and working
area with other exterior interference via frequency selector and
digital processing.
6.
Flexible array—traditional and unique array
method:
It has multi-array measurement method:
traditional and original electrode array method, which has good
geological effect and easy explanation. It makes big achievement in
solving problems about the direction, depth and thickness of ore
vein
7. Remarkable
effect:
Through
the relative physical parameters variation like different
conductivity between ore and non-ore object, it can get the
relative information as ore vein direction, buried depth, thickness
and deposit etc. In more than *0 years' practice, we gained
outstanding achievement and customers' common
praise.
Main
technical parameters:
1.
Automatic noise reduction, super 5 shifts anti-jamming design, fit for
various geological conditions.
2. 3 frequencies or *0 frequencies
measurement synchronously.
3. Operating functions are all on the LCD
screen, easy operation.
4.
