PQWT-M mobile water detector for 100/200/400m

Hunan Puqi Geologic Exploration Equipment InstitutePQWT-TC Water Detector PQWT automatic mapping water detector is based on the Earth's electromagnetic field as the field source, based on the difference in the conductivity of different underground geological structures, and by studying the variation law of the electric field components at different frequencies to study the geological structure and changes, to find groundwater resources by scientific method. Changes in geological structure are displayed in real-time through multiple curves. Automatic form mapping geological profile by one key...

Hunan Puqi Geologic Exploration Equipment Institute The working principle The machine is working by Natural electric field frequency selection method. The data is Self-potential, and unit is millivolt. 1 .The two electrode insert the ground soil and it forms a circuit, The machine collects earth Self-potential difference data (you can regard it as resistivity if you can not understand) 2. The machine installs the software to directly from the profile map and curve in the instrument. The map shows the underground geologic structure. 3. We will observe the profile map and curve to find the abnormal...

measurement point, The vertical line of profile map is measurement depth) 1. Blue, light blue just meaning it is low resistivity, like water, soft mud, and some mineral are all low resistivity, so not just this kind of color is water; 2. Yellow means the middle resistivity, like rock or something; 3. Red means the high resistivity, like the cavity or hard rock; So not each color could stand for anything, the map just could help us to analysis the geological structure, need to combine the local geological, that's the reason We hope before using this machine, please measure the drilled well at...

Hunan Puqi Geologic Exploration Equipment Institute Geologic knowledge: water/mud—low resistivity—stand for blue Rock —middle resistivity—stand for yellow fautt Cave—high resistivity-stand for Red From map:Horizontal is measure point;Vertical is detect depth From Curve:Horizontal is measure point;Vertical is resistivity value As all know the whole Rock will not gather water,it should gather at the crack of rock. From Curve, 13point is lot of lower resisitivity like "v" shap. From Map,13point is at the crack of the rock, so 13point is the better for drilling well.
