Measurement of pH of RO/DI water will not give you a factual result because the pH reading is going to be dependent on salts in the water
No. pH measures the concentration of H+ ions in solution, not salts. RO, DI or other water can all be measured with a meter calibrated for the expected range. RO should be theoretically 7.0 and will be dependent on dissolved gases (O2, CO2) contributing ions to the mix.
TDS will measure salts and other dissolved solids in solution.
