Magnetic surveying is a cornerstone of modern geophysics, helping scientists and engineers map underground resources, study tectonic movements, and even locate historical artifacts. At the heart of this technology lies the cesium optical pump magnetometer-a device so precise it can detect changes in Earth's magnetic field a million times smaller than a fridge magnet's pull.
Unlike traditional magnetometers, cesium-based sensors use laser-polarized atoms to measure magnetic fields. Here's why that matters:
No moving parts = near-zero maintenance.
Instant readings-no warm-up time required.
Unrivaled precision: Detects shifts as tiny as 0.0006nT (that's 0.0000000006 Tesla!).
Designed for marine research and offshore industries, the GD02 tackles challenges like:
Oil/gas reservoir mapping: Its 10000-105000nT range and <2.5nT absolute accuracy make it ideal for subsea mineral surveys.
Underwater archaeology: Helped locate historic wrecks by spotting iron debris fields.
Key Features:
1. 500m waterproof rating (deeper versions available).
2. Auto-hemisphere switching-works flawlessly near the poles.
3. Lightweight tow body (15kg) reduces drag for ships/UUVs.
Defense applications: Detects metallic objects (e.g., mines, submarines) with gradient tolerance up to 40,000nT/m.
For land-based or aerial surveys, the GD03 shines with:
Drone compatibility: Weighing just 280g, it's perfect for airborne mineral prospecting.
Rapid setup: Pre-calibrated out of the box-just attach to your platform.
Budget-friendly: Delivers lab-grade data without the six-figure price tag.
Energy Sector: Map oil/gas deposits or wind farm seabeds.
Civil Engineering: Inspect bridges, tunnels, and pipelines for hidden corrosion.
Environmental Studies: Track magnetic pollution near industrial sites.
