Excuse my butting in but the only way to *determine* anything with your EIS is laboratory analysis. If you've got a pocket full of money and are willing to get *several* samples analysed, go for it, but if not, then don't worry about it, just keep using that meter. Jeez, if I didn't know better I'd be thinking someone's trying to put the frighteners up people again, only this time it's about meters.
Meters are NOT accurate, only laboratory analysis will result in any degree of accuracy, but meters are the best to be had for the home producer, regardless of their inaccuracies. uS readings are multiplied by whatever figure you find in the public domain, pick one, there's plenty to choose from out there. As with most things EIS related, there doesn't even seem to be a consensus on THAT! If it's a ppm meter, then just double that reading, how *accurate* does one want to be in the backyard? Unless of course this place is exclusive to scientific types? I used 3 meters for quite some time to compare each of em! And I did that so I know I can separate myth from fact when marketers go on about what meter to buy and what not to buy. And don't believe a *particular* marketed meter will read EIS to the 'ppm', cos from my experience...and laboratory analysis of several samples...they don't! Just keep using that meter and aim for repeatable results, and recheck your solutions each day for several days taking note of what goes on over time, and if you find mud or gravel in the bottom of those storage containers...then you're gunna have to reassess what your doing. And clean those probes on that meter after every time you use it. Jeez, I think I must've got outa the wrong side of the bed this morning! <g> N.

And note that meters only tell part of the story. They do NOT measure the presence of particles or organic impurities. So as it says below "a cup of distilled water that contains a tablespoon of sugar and finely powdered glass may display a ppm reading of near zero even though its obviously not pure." David Heres some stuff about meters... Many people think that a PPM meter gives a definitive reading of the purity of water. This is not true. A ppm meter can only detect those dissolved impurities that raise the electrical conductivity of the water. So a meter can only determine the ppm of the dissolved NON-ORGANIC impurities (e.g. dissolved salts) because only these impurities raise the conductivity. It cannot detect the dissolved ORGANIC impurities* that may also be in the water (e.g. sugar or rotted leaf litter). Nor can a ppm meter detect the microscopic solid particles that may be in the water (i.e. the grit). So a cup of distilled water that contains a tablespoon of sugar and finely powdered glass may display a ppm reading of near zero even though its obviously not pure. So, when using a ppm meter to measure water purity, you have to know if the dissolved organic impurities and the fine particles have been removed along with the salts. The only way to remove all these impurities is with a high quality reverse osmosis/deionisation system or with careful steam distillation. The shortcomings of meters mentioned here should especially be considered when measuring the purity of rain water. Although the rain water may initially be pure, it can become significantly contaminated by organic impurities in the gutters and the tank. Although these impurities are not detectable by the meter they can have quite a detrimental effect on colloidal silver production. (* One qualification to the comment above about the 'non conductivity' of organic impurities concerns the presence of acid. Any acid raises the electrical conductivity of water and can induce a completely meaningless reading on a ppm meter. While organic impurities usually do not register on a ppm meter, a few drops of, say, acidic lemon juice in a glass of water will produce readings in the 100's.) -- The Silver List is a moderated forum for discussing Colloidal Silver.
