DZD-6A Water Detector / OEM / In Factory Price:
1. Brief Introduction:
The DZD-6A is a versatile geophysical instrument that utilizes the apparent resistivity method and IP (Induced Polarization) survey. It uses a DC power supply to send current into the ground, and after receiving and processing the data, it can identify any anomalies. The device supports 10 different electrode arrays, including 4-electrode Vertical Electrical Sounding (VES), 3-electrode VES, 4-electrode profiling, combined profiling, mid-gradient, 5-electrode VES, buried electrodes, dipole-dipole, two-pole, and surface-borehole electrical methods. The detection depth varies depending on geological conditions, typically ranging from 500 to 1000 meters.
2. Main Applications:
This instrument is widely used in detailed and general surveys for both metallic and non-metallic ores. It is also applied in underground water exploration, urban prospecting, railway and bridge engineering investigations, geothermal studies, and coal goaf detection. Its versatility makes it an essential tool for various geophysical applications.
3. Key Features:
- Compact and lightweight design, integrating transmitter and receiver in one unit, capable of performing apparent resistivity and induced polarization measurements simultaneously.
- Supports multi-parameter measurement, including first potential (Vp), SP (Vsp), current (I), apparent resistivity (Ro), apparent polarizability (Ms), half-time (Th), degree of decrement (D), degree of deviation (R), and stimulation parameters (Zp).
- Flexible operation with full digital automatic measurement, featuring auto-compensation for SP, drift, and electrode polarization.
- Large LED screen displaying up to 9 electrode arrays, with keyboard input for array parameters. After each measurement, it displays resistivity curves, apparent polarizability curves, and more.
- Easy data interpretation with storage capacity for 4800 points, each containing 22 data entries. Data can be transferred to a PC via RS-232 for further analysis using specialized software.
- Robust design with a large display, sealed multi-layer panel, and internal power supply with over-voltage and over-current protection, suitable for diverse field environments.
