Geotech Launches GIM-5 Multi-Channel Resistivity & IP Meter for Global Geophysical Markets

High-precision instrument integrates resistivity and induced polarization for mineral exploration, hydrogeology and environmental monitoring worldwide. End Quote

(1888PressRelease) September 14, 2026 - Geotech, a leading manufacturer of professional geophysical exploration instruments, today announced the global launch of its GIM-5 Multi-Channel Resistivity & IP Meter, a next-generation field survey instrument built to deliver high-accuracy subsurface imaging for mining, environmental and civil engineering projects. The GIM-5 features 12-channel parallel acquisition with 24-bit A/D conversion, delivering 0.01 Ω·m resistivity resolution and supporting up to 1,024 electrode configurations for electrical resistivity tomography (ERT) and vertical electrical sounding (VES) surveys. Its built-in induced polarization (IP) module captures chargeability data with millisecond time resolution, enabling detailed differentiation of sulfide ore bodies, clay formations and contaminated groundwater plumes.

Built for rugged field conditions, the GIM-5 operates across a temperature range of -40°C to 70°C with an IP67-rated dustproof and waterproof enclosure. It supports both surface and borehole electrode arrays, with a maximum exploration depth of 1,500 meters depending on array geometry and local geological conditions. The instrument's low-power design extends field battery life to 72+ hours of continuous operation, reducing downtime in remote survey locations.

"The GIM-5 redefines field efficiency for electrical geophysical surveys," said the Product Director at Geotech. "Traditional single-channel instruments require days to complete large-scale ERT projects. Our multi-channel architecture cuts survey time by 70% while maintaining laboratory-grade precision, making high-resolution subsurface imaging accessible to teams of all sizes."

For mineral exploration teams, the integrated IP function helps identify buried sulfide deposits and distinguish ore zones from barren host rock, reducing unnecessary drilling costs and improving exploration success rates. In hydrogeological applications, the GIM-5 delivers high-resolution aquifer mapping and groundwater contamination plume tracking. It also supports engineering geology projects including foundation investigation, karst cavity detection and landslide stability assessment.
