by this do you mean they are using a electronic tester to measure the resistance of the water to "allow current" to determin the quality of the water?

If so this will only tell the amount of metals in the solution, or rather lack of metals. Phosphates will not conduct electricity so they will not me measured by a resistance based tester.
