What Is pH?
pH, or Potential of Hydrogen, is a measure of the acidity or alkalinity of a solution. Aqueous solutions at 25°C with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline).
A pH meter can be very useful in a variety of situations, from measuring drinking water to pools water, or for many industrial or commercial applications.
HM Digital’s PH-200 is an extremely reliable pH meter that is very easy to use, easy to calibrate and offers excellent repeatability. Compared to chemicals or paper strips, where questionable color comparisons are required, with the PH-200, it’s a simple matter of turning the meter, dipping it in the liquid and reading the pH value on the LCD display.
