Description

We are one of the largest  professional and reliable  manufacturers of geophysical prospecting instrument in China,dealing with this line for *0 years, such as geophysical instrument,water detector,mimeral prospector, resistivity meter, resistivity IP and SP system, resistivity, IP, SP, TEM survey, magnetometer, seismograph, gravity meter, proton magnetometer, drilling equipment, and element analyzer etc.

Principle
     AD-C Natural VLF water detector uses relative parameters like resistivity variation produced by natural electrical field and different geologic structures(underground water is benign conductor)to determine the water(bedrock fracture water, carst water, pebble bed water etc.) we are seeking. It can know relative information like water location, depth and water outflow etc. Comparing to other water detectors, it has obvious advantages: fast, high accuracy, check full information, portable, simple operation and so on.

Main application

    1. Applied in underground water detection 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 features
   1. Fast and high efficiency:
Complete about ***0m profile measurement in one day to realize geological abnormity in different depth, the prospecting speed and efficiency is improved about *0 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 *0 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.**1mV, high precision ±*0%.
    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.

Technical parameters
   1.Automatic noise reduction, super anti-jamming.
   2. Measurement of 3 frequency (*5Hz, *7Hz, **7Hz) or *0 frequencies measuring synchronously.

   3. Operation functions are all displayed on LCD, you can see them directly.

   4. Automatic measurement, data storage and curves mapping. Data record is no need. The data will not loss even power off.
   5. The data storage capacity: *0 measured curves in three frequencies and *0 measured curves in multi-frequencies measurement.

   6. Curves and data can be displayed; you can also transmit data by USB port and map or print in computer.

   7. Rechargeable batteries to supply power.
   8.Electrode detection and power monitoring function
   9.Measuring range: 0.**1mV~**5mV (exchange range automatically)
   *0.Measurement resolution: 0.**1mV 
   *1.Measurement accuracy: ± 5% ± 3 bytes
   *2.Input impedance: ≥ *0MΩ 
   *3.Whole operating temperature: **0 ?~+*0 ? 
   *4.Working Humidity: *5% 
   *5.Whole weight: 1.*8Kg (batteries excluded), size: *4CM**3CM**6CM
