The device uses a system of optical cells to measure the turbidity of the water column inside a borehole and the possible presence of tracers. Can be detected and recorded simultaneously the presence of substances such Uranina, and Rhodamina and Tinopale.
This type of log, as for the tracer tests, can be performed up to a pressure of 7 bar.
♦ Hydrogeological studies and geothermal resources;
♦ Permeability and pumping tests.
