T-VLF System
VLF System using Radio wave for high productivity surveys in groundwater, environmental and mineral exploration using Tilt mode and Resistivity mode. It contains two inclinometers to correct tilted positions of the instrument and no orientation of the operator is desired with respect to the direction of the transmitting station as to measure three components of the magnetic field. The Electromagnetic receiver measures the VLF Radio Waves in the frequency range of 10 – 30 KHz. 2. Selection of frequency through the keyboard, by step of 100 Hz; and simultaneous measurement of two frequencies. It also measures two components (one electric line & one magnetic) in Resistivity Mode.
