Resistivity / Conductivity Testing

Probedrill have a resistivity/conductivity module which can be used to evaluate the degree of contamination of a polluted environment.

The conductivity cone can evaluate the degree of contamination of a soil containing electrolytes (the compounds dissociating into ions in water).  Since hydrogen and hydroxide ions have the highest conductivity, the easiest way to detect inorganic acids, hydroxides and their salts in soil, is to use this method.  This method may also be useful in identifying zones with increased concentrations of nitrites and nitrates, sulphates, calcium and magnesium compounds or concentrations of heavy metal.

The conductivity method can also determine the range of fresh and salt water in sub-soil.  The presence of sodium and chlorine ions in the salt water increase conductivity and therefore can identify zones of where salt water occurs.

There are many applications where the conductivity cone can be used.  Probedrill can also complement this testing by providing Soil or Water samples of laboratory testing.
