Di water resistivity range

WebMar 8, 2024 · 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. WebThe resistivity of the water sent to the rinse tank is far less important than the resistivity of the water that is on the parts when they leave the rinse tank. This is the reason that in many critical applications, the final rinse is a spray with DI water, rather than an immersion rinse. For example, you could send 1 Meg-Ohm-cm water to an ...
