WCZ-1B proton magnetometer is a upgrade model base on WCZ-1, which has a more compact design and internal battery. Magnetic measurement precision is ±1nT and resolution reaches 0.1nT. Boasting large storage, high resolution, and flexibility, WCZ-1B can measure total field intensity, horizontal or vertical gradient component with resolution of0.1nT by altering sensor structure. 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. • Small ferrite body finding.
