VLF Electromagnetic Instrument is to utilize the electromagnetic wave transmitted by VLF radio station as field source to determine the changes of various parameters of VLF electromagnetic field under the influence of geologic body.
Mainly used for detecting underground ore body and caves, and for rapid resistivity mapping; also has good prospecting effects on searching of underground pipes, water leakage of building foundations and collapse foundations.
The instrument is compact in size and light in weight, easy for operation, with stable and reliable performance, multiple function with one machine, with flexible operating method.
Technical Specifications
Working Frequency: 17.4 KHz, 22.3 KHZ, two frequency spots.
