pH Testers-Meters
Plantlighting Hydroponics provides inexpensive solutions for accurate pH measurement. pH (potential of Hydrogen) measurement reveals if a solution is acidic or alkaline (also base or basic). The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic solutions, while higher readings indicate alkaline or base solutions. Some extreme substances can score lower than 0 or greater than 14, but most fall within the scale. Choose Bluelab, Hanna, or Milwaukee test instruments.
