ATEM-4 Transient Electromagnetic Prospector

Main Function:

1. 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.

2. Detect various metal and non-metal ores, underground water, underground water-filling karsts and steep dip geological formation;

3. Especially applied in coal bed and coal goaf area and water-filling area detection;

Main Advantages:

1.Advanced interpretation software system: include half-space interpretation software system for ground work and full-space interpretation software system for underground work (coal mine tunnel, tunnel, military affairs etc.)

2. Industrial PC as main controller and Windows as control panel, with high automatization degree;

3. Receiver has super low noise preamplifier; you can choose proper stacking times at random to guarantee measurement accuracy and wide dynamic;

4. The power supply working method is “Big currency small coil”, and it first realizes 200A big currency continuous square-wave power supply in the world;

5. The display is reflective LCD, the power consumption is extremely low, so we can use it in the sunshine, especially applicable in field open-air environment;

6. Use large capacity electronic disk as memory instead of hard-disk to make sure the security of equipment even in field strong vibration transportation;

7. Multiple anti-jam technology to make detect and explanation result more accurate;
