NEP-A Natural VLF Prospector 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.

NEP-A Natural VLF 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. The speed is 10 times more than traditional DC resistivity prospector, and it is your useful assitance in ore prospecting. More than 20 years’ practice proves that it is a state-of-the-art portable earth resistivity meter and gains customers’ common praise.

 

 2. Main 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.

1.Automatic noise reduction, super anti-jamming.
