AMT-6 Audio-frequency magnetotelluric system is a new generation product based on the magnetotelluric sounding method, MT system, AMT system, frequency sounding method and NEF system, it judges and analyzes the geological abnormity we need to search by measuring relative parameters(such as resistivity) change generated by different structure. And according to the geological theory and qualitative and semi-quantitative interpretation of measurement data, we can estimate underground abnormal geological conditions like location, direction, buried depth, shape and size etc..

Features:
1.Fast and high efficiency: the prospecting speed and efficiency is improved about 10 times more than traditional resistivity method.
2.Easy to carry: the weight of complete set is less than 5kg, it’s very easy to carry
3.Easy operation: user-friendly interface, high-speed CPU, menu prompts, learn the operation into two minutes.
4.High accuracy: with imported core parts, FFT digital filtering technology, high-performance amplifiers and AD converters, the resolution is up to 0.1uV±1%, and the fixed error of frequency is only 0.1%.
5.Wide frequency range: the frequency respond range is from 0.1Hz to 5KHz, to greatly improve the surveying depth.

Applications:
1. Widely used in the detailed and general survey of energy minerals (metal ore, non-metal ore, oil and natural gas, coal etc.) to decrease the venture of mineral investment and improve exploration success rate and scientificalness.
2. Applied in the detailed and general survey of underground water to increase the success rate of drilling water.
3. Widely used in the detailed and general survey of hydrologic geology(such as coal goaf, groundwater disasters, dams hidden danger, mountain landslide etc.) to prevent the disaster.
4. Also used in engineering geological prospecting, archaeological, city exploration, non-metal pipe survey as well.
