Portable detector groundwater for detective instruments underground water detection
The main purpose
1. It is widely used for detailed and general surveys of underground natural energy such as groundwater and geothermal energy to improve the success rate of drilling and water resources.
2. It is widely used for detailed and general survey of mineral energy (metal ore, non-metallic ore, oil and gas, coal mine, etc.) to reduce the amount of geological drilling, reduce the risk of mine investment, and improve the scientificity and success rate of mineral investment.
3. It is widely used in the detailed and general survey of hydrogeology such as coal mine goafs, groundwater disasters, hidden dangers of dams, fault zones and collapse columns, landslides, etc.
4. Identify the hidden hazards of the reservoir dam foundation and flood control dike, look for fault zones and collapse columns, landslides, coal mine goafs, find geothermal and other hydrological, engineering geological exploration.
5. It is also used for detailed and general surveys such as railway and bridge engineering geological exploration, urban geophysical prospecting, archaeological excavation, underground pipelines, etc.
1. One-key charting function, can generate isoline color maps on site without a computer host.
2. Support online software update and device firmware upgrade.
3. Dense frequency point setting, 50 frequencies, layered and meticulous, clear contour map can intuitively reflect the abnormal point.
4. With GPS positioning information, easy to locate a specific location.
5. The instrument host Windows10 operating system is more intelligent.
6. Good accuracy and high accuracy: high-performance amplifiers and imported core components, high-performance AD converters, FFT digital filtering technology, resolution up to 0.001mV, high-precision measurement of ± 1%.
7. Wide frequency range: The frequency response range is 0.1-300KHz, which greatly improves the exploration depth.
8. Strong anti-interference ability: high-performance wave-limiting circuit, power frequency 50HZ suppression ability> 100dB suitable for various geological environments.
9. Black box single electric level rod measurement, no need to pull the wire.
10. Automatically store data: The instrument does not need to record when measuring, it can automatically store data, the data will not be lost after power off and power off.
