Introduction
DSHF600 Natural VLF Water Detector is the other upgrade product on the base of continuous improvement and enhancement. The module of full imported IC control and filtration completely reaches international leading level to fixed machine filtering of frequency; and can be got perfect stability and accuracy in data measurement. The instrument is also further improved in shielding interference signal and design of anti-jamming.
It is more convenient as it realizes PC communication in latter data processing. It has many advantages like simple operation, easy to carry, stable data, strong anti-jamming ability, high accuracy, fast speed etc. Comparing to traditional electrical prospecting equipment, it is 10 times more quick while the weight is 10 times less, which saves large amount of time, manpower and materials for field survey. It is your optimal assistant in geophysical survey.
Main Principle
DSHF600 Natural VLF Water Detector uses relative parameters like resistivity variation produced by natural electric field and different geologic substance to determine the geological abnormity we are seeking. Through the relative physical parameters variation like different conductivity between ore and non-ore object, it can get the relative information as ore vein direction, buried depth, thickness and deposit etc. In more than 20 years' practice, we gained outstanding achievement and customers' common praise.
Function
1. Applied in underground water detect to meet the demand of drinking water, industrial usage and agricultural irrigation.
2. 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.
3. Also used in engineering geological prospecting, disaster geological detect, coal goaf, archaeological mining, city exploration, non-metal pipe survey as well.
Main Advantages
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 operate:
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
7. Remarkable effect:
Through the relative physical parameters variation like different conductivity between ore and non-ore object, it can get the relative information as ore vein direction, buried depth, thickness and deposit etc. In more than 20 years' practice, we gained outstanding achievement and customers' common praise.
