SWT’s DI Lights are an economical method of monitoring water quality via resistivity / conductivity / TDS. The bright red or green visual output is easy to read. The monitoring is simple: the green light indicates the water resistivity is above the threshold value; the red light indicates that it is below. WebAs soon as the DI water comes out of the system and is exposed to the atmosphere, it dramatically loses resistivity as it quickly becomes ionized again. It is also true that it will lose resistivity the moment that it comes in contact with any container due to contaminants inherent in the bottle. facts about exxon mobile
