Glad I have it!
Was shocked when I tested the first batch of colloidal silver I made before I got the tester! It tested at 4 ppm, rather than the 19+ ppm I had supposed. The second batch IS up to snuff! Thanks!Verified purchase: YesCondition: New

MORE HASTLE TO GIVE REVIEW WITH PASSWORDS ETC. THIS MY LAST REVIEW !
TESTER WORKS GREAT FOR SPECIFIC COLLOIDAL SILVER PPM. *RE: OTHER LIQUIDS TO MEASURE PPM.* CALIBRATION NEEDED TO SPECIFIC MATERIALS WITH CATALYST USED MAY DIFFER . OTHER PPM. CO-EFFICIENT MATH FACTOR # MAY BE REQUIRED WITH METER AS IS .Verified purchase: YesCondition: New

Easy to use.
I ordered this to test my silver I have been making. I learned that it was not as strong as I thought. Takes the guesswork out of Colloidal silver production.Verified purchase: YesCondition: New
