NEF-800 Mine prospecting instrument & Natural VLF Water Detector:
NEF-800 Mine prospecting instrument & Natural VLF Water Detector 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.
Terials for field survey. It is your optimal assistant in geophysical survey.

NEF-800 applications
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.

1. Fast and high efficiency: Complete about 4000m profile measurement in one day to realize geological abnormality in different depth, the prospecting speed and efficiency is improved about 10 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 10 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 0.001mV, 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 veinding achievement and customers' common praise.

technical parameters
1. Automatic noise reduction, super 5 shifts anti-jamming design, fit for various geological conditions.
2. 5 frequencies or 30 frequencies measurement synchronously.
3. Operating functions are all on the LCD screen, easy operation.
4. Automatic measurement, data storage and curves mapping. No need to record data and the data can be transferred to U disk directly.

5. It can store 5 frequencies measuring data of 30 curves and multiple frequencies data of 30 curves, the data and curves can be displayed.
6. Use film switch panel to make usage more stable and convenient, the appearance is beautiful.
7. Power supply: by large capacity chargeable lithium batteries.
8. Electrode test and power monitor function.
9. Measuring range: 0.001mV~355mV (auto range transfer)
10. Resolution: 0.001mV
11. Measuring voltage accuracy: ±1% ±1LSB
12. Measuring currency accuracy: ±1% ±1LSB
13. Input impendence: ≥50MΩ
14. Working temperature: -10°C~+50°C
15. Working humidity: 95%
16. Whole weight.2.5kg, size: 31cm*23cm*10.8cm.
17,Detect depth:600M
The principle of natural electrical field prospecting and manual geo-electrical method is basically the same. But they also have main differences:
Traditional geo-electric prospectorNEF800 Underground Water Detector:
Heavy device and complicated wiring due to manual power supply.No need power supply, stable signal, use natural electric field and 20 meters receiver pole to complete survey through special amplify method. Very convenient!
Need 3-5 persons or more to operate then cause heavy work and low efficiency.1~2 people are enough to finish the work, fast data acquiring.
Heavy, about 50-500KG, hard to move.Light weight, less than 5KG, easy to carry.
Low efficiency caused by heavy device and trouble arraysLight, flexible arrays, special fine and rough measurement method to improve work efficiency up to 10 times
