Unfortunately, up-to date device must be installed in chambers or cave abysses or roads, because measuring sensor with adjustment parts is (40-60)x(40-60)x30 cm box and vertical measuring base must be as long as possible. The lenght of our measuring bases is from 5 m up (chamber in old mine) up to 30 m (abyss in cave). Borehole is not sufficient for such measurement yet. Maybee in the future by next generation of apparatus.

Only PC, which controls apparatus and collects data, is power consuming. We use standart PC without monitor and we supply cca 150 W. The second generation is already based on low-power one board PC, which has only 15 W and is supplied by solar panel. We are preparing it for the measurement in desert areas and caves outside civilisation.
