DDS-3 Very Low Frequency (VLF) Electromagnetic Instrument
Product Description
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.
ADS-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.
Features:
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.
Measuring parameters: magnetic field horizontal and vertical components, polarized ellipse inclination and ground electric field horizontal components.
Simple operation, stable and reliable, multiple applications, and flexible usages.
