Multi-Function Digital DC Resistivity/IP Meter – Advanced Geophysical Exploration Tool
Description of Multi-Function Digital DC Resistivity/IP Meter – Advanced Geophysical Exploration Tool:
The WDJD-4A Multi-Function Digital DC Resistivity/IP Meter is a cutting-edge geophysical instrument designed for high-precision subsurface exploration. Built on the foundation of the WDJD-3A, this advanced model offers higher accuracy and more measurement parameters, making it ideal for metal and non-metal mineral resource exploration, urban geophysical surveys, and hydrological studies. With its enhanced anti-interference capabilities and diverse working modes, the WDJD-4A delivers reliable data even in complex electromagnetic environments.
Applications:
Mineral Exploration: Accurately locates metal and non-metal deposits.
Groundwater Detection: Identifies underground water sources for resource management.
Infrastructure Projects: Assesses subsurface conditions for dams, bridges, and railways.
Geothermal Exploration: Maps geothermal reservoirs for energy extraction.
Features of Multi-Function Digital DC Resistivity/IP Meter – Advanced Geophysical Exploration Tool:
High Precision: Measures voltage and current with 0.1 microvolt and 0.2 microampere resolution.
Advanced Anti-Interference: Suppresses industrial frequency interference by ≥80dB.
Multiple Working Modes: Supports resistivity, IP, and imaging modes for versatile applications.
Large Storage Capacity: Stores up to 1GB of data for extensive surveys.
Portable Design: Lightweight (≤4.4kg) and powered by a 12V rechargeable battery for up to 30 hours.
