**Product Information**
Model NO.: DZD-6A
Trademark: GOLD
Origin: China
HS Code: 9015800090
**Geophysical Equipment with Resistivity and Induced Polarization Surveying Equipment – Water Detector**
**CHARACTERISTICS:**
1. This advanced geophysical instrument utilizes apparent resistivity and induced polarization methods, making it ideal for a wide range of applications such as mineral exploration, energy resource surveys, urban geophysical investigations, railway and bridge engineering studies, and more.
2. It is specifically designed to locate groundwater, addressing drinking water issues for humans and animals, as well as industrial and agricultural water needs. It also helps identify hidden risks in reservoir dam foundations, flood control dikes, fault zones, collapse columns, landslides, coal mining voids, and geothermal areas.
3. The equipment is equipped with accessories like a 60-channel or 120-channel multiplex electrode switch, which can be used for multi-electrode resistivity survey systems, offering flexibility and efficiency in field operations.
**FEATURES:**
· 1) Compact and lightweight design: Combines both transmitter and receiver in one unit, allowing for simultaneous measurement of apparent resistivity and induced polarization.
· 2) Multiple measurable parameters: Includes primary field potential (Vp), self-potential voltage (Vsp), supply current (I), apparent resistivity (Ro), apparent polarizability (M1~7), half-life time (TH), damping degree (D), deviation (R), and synthesized excitation electron parameter (Zp).
· 3) Easy and flexible operation: Features automatic digital measurement, with built-in compensation for self-potential, drift, and electrode polarization. A large LCD screen displays nine different pole distributions. Users can input parameters via the key panel, and after each measurement, the system directly displays curves of apparent resistivity, polarizability, and half-life time.
· 4) Efficient data interpretation: The device can store up to 1,200 measurement points. With a serial port RS-232, data can be transferred to a computer for further digital analysis using specialized software.
· 5) Robust and user-friendly design: Equipped with a large screen and a multi-layer touch panel with thin-film sealing. The power section includes over-voltage and over-current protection, ensuring reliable performance in various field environments.
