Hi all, where I can find how the electric conductivity of water is measure.?
I know that it is stated as mS/cm
for mS as miliSiemens.
I do not need to measure it , I just want to compare between a normal soft drink water as it comes on the 20 liter bottles used on cold or warm water dispenser , among some tap water on sites that it is not soft.
I have the sample from each site and the drink water .
Thank in advance.
