Jr, PWT means Pure Water Tester. Absolutely pure water will not conduct electricity. It is very difficult to make as water is a universal solvent. Pure water would measure in many many millions of ohms. In fact it could not be measured. However water that pure will leach glass or any metal until it reaches a lower value of resistance.
As to what is measured depends on the material used in the condensing coils of the still. Some stills use copper, others use stainless steel and some use a borosilicate glass (hard glass like pyrex). So one has ions of some material in the water that has reduced its resistance or increased its conductivity. These terms are reciprocals. Does that answer your question?
