Can this be used to check for collodial silver in the 10 ppm range in a solution of distilled water?

FROM HM DIGITAL: Yes, any of our TDS meters can be used for checking colloidal silver in any range (up to the meter's max). Since distilled water will be virtually devoid of TDS and register 0 ppm (potentially 1 or 2 ppm), if you add 10 ppm of colloidal silver to the water, it will show as 10 ppm on the meter. One thing to note is that the TDS-EZ is one of our most basic TDS meters and does not have ATC (Automatic Temperature Compensation), which means it will not automatically compensate for temperature discrepancies off the baseline of 77F (25C). For everyday drinking water testing, this is not an issue, but for sensitive testing, it can be. Therefore, if the water will be much hotter or colder than 77F, it's suggested to get a more advanced meter, such as HM Digital's AP-1.

Im the last person to answer this one. Both boxes i purchased tested on distilled water, tap water and my spit the same reading. i never could get the strips to change from the same reading. I do know under normal testing (other strips i did notice a change when water was tested).

I don't know, but the silver solution it makes works. Colds get knocked out quickly & cuts heal just fine. I just make a batch as needed. If I need to store it (lack of time), I make it higher ppm & dilute as needed. It passes the laser pointer test.

Ed jones beat me to it with his response. The type of water filtered varies in the field every time. In a lab, not very useful. But I agree with you there should be some type of standard test. Maybe there is?

Not sure, it works good on silver but does not get a real deep clean on certain items. I may not be leaving it to soak long enough or the chemicals may not be strong enough in my bottle.

This is not the divice to use. It measures total desolved solids. If the impurities are not desolved, i.e.an emulsion, it won't work.

That's a great question, but unfortunately, I don't know the answer because I've only used it on silver coins. Sorry.

Not really. The calibration fluid (distilled water) and the test sample are supposed to be at the same temperature. For all practical purposes they will both be at the temperature of the refractometer since they are such small samples.

no...not likely. You must use absolutely mineral-free water....the metals or other ingredients will not permit the proper action of suspension of the silver particles in water. Even the osmosis method of distilling is not good enough. The water to use must be steam-distilled to work correctly. nancy morse.

I haven't used mine yet but as I understand most all metals. It has different settings for what particular metal you are wanting to detect.

All this device does is measure mow many dissolved solids are in the water, not what they are. It could be iron, lead, calcium, chlorine, benzine, whatever. what your looking for is a gas spectrometer. Very much outside the range of handheld gadgetry.

According to the Encyclopedia of Chemical Technology, "Size of a silver colloid is 1-100 Nanometers." Natural Path / Silver Wings' colloidal silver is guaranteed to range between 1-10 Nanometers. The mean (98%-99% of the solution) silver particle size is 2 Nanometers. Darkmatter777 is correct 0.002 Microns is the same as 2 Nanometers. Thank you Sandra and Darkmater777.

Yes it can detect gold, silver, brass & copper...nickel & zinc clad objects...alongwith aluminum and dicast metals...

Depends on how much iron is in your water. I use a tds meter, and my well water has 380 ppm tds. After Ro/Di highest I've seen is .001 tds with this unit. Hope that helps a little. I would check tds in your water before making a decision.

Okay Karen! Here's what the label says: 24 ppm patented Silver Solution (de-ionized water and silver), TEA (wonder what that stands for?) and Carbomer. It doesn't really tell us MUCH, but it sounds to me like it's probably safe...it sure does work for me!!! :-) Have a good day, 'k? Sincerely, Glenice Loux

I don't know. It is for metals and I suspect you could contact the company and ask

The TDS of my tap water is 430ppm; all those minerals would surely shorten the lifespan and effectiveness of this unit. Hence I use RO water [I have a unit which I normally use for my aquariums] which has a TDS of below 10ppm. You can buy distilled water although not sure how costly that is in the longrun.
