Place the probe in the solution and read TDS in ppm. Change to EC on the meter and read EC in mS/cm. Conversion factor = ppm / EC. [Note: mS must be converted to use: One milliSiemen = 1000 microSiemens (1.0 mS/cm = 1000.0 µS/cm) According to the chart below: 1.0 mS/cm...
TDS Water Chart So what level of TDS is good or acceptable? In a study by the World Health Organization, a panel of testers came up with a chart about the preferable level of TDS in water: Ref:World Health Organisation Here is also another table on how much TDS is present in ...

Since the relative density of water is related to its dissolved solids content, each increase of 0.0001 relative density at 15.6°C is approximately equal to 110 ppm. Of course, the sample must be cooled down to 15.6°C or a correction chart used(supplied with the hydrometer) for proper ...
The chart to the right shows some common chlorine/chloramines reducing agents. You will note that metabisulfites and bisulfites are efficient reducers, however it should be noted that some studies have shown these to lower dissolved oxygen levels. I have never had a problem with this due to ...
