Main Applications:
VLF electromagnetic prospector applies electromagnetic wave transmitted by very-low frequency radio station as field source, to measure the many parameters change influenced by various geological bodies.
DSHS-3 VLF (very low radio frequency) electromagnetic prospector is applied to explore underground minerals and caves, fast resistivity mapping; it also has a good effect to explore underground tubes, substructures and leaking dams.
Advantages:
1. Measuring parameters: magnetic field horizontal and vertical components, polarized ellipse inclination and ground electric field horizontal components.
2. The attenuation of electromagnetic waves transmitted by VLF broadcasting station is small; the field intensity is even, low noise and long working time. It can be used in anywhere.
3. Simple operation, stable and reliable, multiple applications, and flexible usages.
Small volume and light weight.
