Can anyone tell me where I can purchase standards solutions so I can verify my water testing?
I use the Lamotte ColorQ 7, which from reading posts, many here have very strong feelings for and against. PLEASE - I do not want this to degrade to why I should or should not use that device. I am an scientist and want to purchase standards solutions and test myself to verify its accuracy and my testing method. I would want to do this regardless of which testing product I owned.
I would like third party solutions. That is, not a solution that is manufactured by one of the test manufacturers, as this would seem to not really be a blind test.
