WCZ-3 is a the latest developed 3rd generation proton-precession magnetometer with the 32 bit SCM technology. It features with multi-functions, fast measuring speed, high gradient range and much light. It integrated with GPS positioning module and GPS adapter. Magnetic measurement precision is ±1nT and resolution reaches 0.1nT. Applications: • Mineral survey, such as iron ore, lead-zinc ore, cupper ore • Mineral prospecting, mineral ore depth, orientation, and continuity, ore shape, size and scale • Oil, natural gas survey, related geological structure. • General survey and local survey, geological mapping • Base station for aerial and marine magnetic survey • Fault detection. • Archaeology. • Hydrogeology. • Engineering survey, such as pipe finding. • Monitoring earthquake auspice, volcano and other environmental disasters. • Locating buried ferrous containers (ex. contaminant waste drums) in environmental surveys. • UXO detection • Locating and tracing buried pipelines in utility-type surveys.
