Measuring resistance is necessary because pure water is ideally around 18 MΩ of resistance and that is well under 1 PPM which is the most TDS meters can detect (see chart below). When measuring the DI water for tracking purposes, the typical filter change out time is when the resistivity is at around 50 kΩ or 10 PPM.
