Nep-a natural vlf prospector

Key Attributes.

1. Simple introduction: It is a design that refers advanced technology home and abroad, solves great subjects on shielding and selective signal processing to amplify in complex natural electric field, and also does multiple anti-jamming as well. Natural electric field prospector is similar to traditional resistivity prospector generally, the biggest difference is applying natural electric as field source and removing heavy power supply, the total set is no more than 5kg. Its main features are simple operation, easy to carry, high accuracy, fast speed, flexible array etc. More than 20 years' practice proves that it is a state-of-the-art portable earth resistivity meter and gains customers' common praise. 2. Principle: It uses the relative parameters like resistivity variation produced by natural electrical field and different geologic structure to judge and analyze the geological abnormality we are searching. The principle is nearly the same with traditional resistivity prospecting, but it enhances the speed more than 10 times. 3. Main application: 1. Underground water detect to meet the demand of drinking water, industrial usage and agricultural irrigation. 2. 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. 3.Engineering geological prospecting,disaster geological detect,coal goaf, archaeological mining,city exploration,non-metal pipe survey etc. 4. Main features: 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 earth natural electromagnetic field as signal source, and the weight of complete set is less than 5kg so easy to carry and use. 3. Easy operation:Equipment is automatically controlled by micro PC. You can learn its operation in 10 min. It will take 2h for person without prospecting experience to finish the relative training. 4. Good precision and high accuracy:Resolution up to 0.001mV, high precision ±2%. 5. Strong anti-jamming capability:With advanced anti-jamming technology, you can get good curves result even in noisy road and high electric jamming area for signal 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.
