American Marine Pinpoint pH Monitor
Product Review (submitted on December 3, 2007):
This product is Awesome! I was always guessing at the color chart of the PH test kit. With this monitor all the guess work is gone.I know just when to add buffer to keep my PH level correct. The only suggestion I would like to make to Pinpoint Marine is that a small internal LED could be added to illuminate the readout @ night.Other than that it is a great product & very helpful.
