Specification :

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. 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.

5. 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:

It will do measurement with resolution up to 0.001mV, high precision ± 2% .

5. Strong anti-jamming capability:

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.

5.Main functions and features:

1. Automatic noise reduction, super anti-jamming.

2. Measurement of 3 frequency ( 25Hz, 67Hz, 167Hz) or 30 frequencies measuring synchronously.

3. Operating functions are all on the LCD screen, easy operation.

4. Auto-measuring, auto-stocked data and auto-mapped curves. It doesn’ t need to record the measured data and the data won' t be lost when power off.

5. It can store 20 curves’ measuring data of 3 frequency and 30 frequencies.

6. Curves and data are displayed on LCD screen. The data and abnormal curves can be also printed by special micro printer or PC printer connected with the printer port, which is very convenient for site data analysis.

7. Power supply: by 4 dry batteries or 4 rechargeable batteries.

8. Electrode test and power monitor function.

9. Measuring range: 0.001mV~ 2550mV ( auto range transfer)

10. Resolution: 0.001mV

11. Measuring accuracy: ± 2% ± 3 LSB
