ATEM-6 Underground mineral detector&Transient Electromagnetic water detector: Detect various metal and non-metal ores, underground water (including carst water), geological disaster survey and steep dip geological formation; Especially applied in coal bed and coal goaf area and water-filling area detection; Search geothermal resources, oil-gas field census and exploration in high-resistance covering area (like carbonate rock, igneous rock and frozen soil covering area), etc. The maximum prospecting depth can exceed 1000m. Main features: First apply 200A large currency square wave to supply power continuously. It uses portable power supply to realize big currency. The power supply working method is Big currency small coil(25 times, 25m transmitting coil), the prospecting depth can reach 1000m, which is specially fit for field terrible working condition and can improve working efficiency obviously. Industrial PC as main controller and Windows as control panel. The supply currency, power pulse width, sampling rate and stacking folds etc. all set by English menu; computer large capacity storage space guarantees large-capacity density sampling. Good security. The receiving circuit applies high performance CMOS chip assemble promoted latest to make total unit perfect function. High sampling rate. Multiple anti-jamming technologies. Advanced interpretation software system.
