NEF-800 minerals detector metal detector underground metal detector
NEF-800 Natural VLF Underground 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 vein
ding achievement and customers' common praise.
