 Shows the sampled water pH.
+The color bands are determined as follows:

+|Corrosive Water (See Note)
+|-

+Note: Ideal pH is between 7.4 and 7.6.  A pH between 7.2 and 7.8 is generally acceptable (though possibly too low or too high).  A pH below 7.2 or above 7.8 may be problematic; verify by calculating the Langelier Saturation Index (LSI).
