Review on PH60F Replacement Pocket Powered ZenTest by David Damico

This Industrial and Scientific product did not deliver. Despite being marketed as a RELIABLE Substance Analysis Instrumentation tool, this analyzer fell short and didn't provide accurate measurements. The pros are that it`s portable and easy to use but the cons outweigh them. It feels flimsy and produces wildly inconsistent results, which won't work for any serious analysis. Save your money and look elsewhere..
