When reading PH on the Luster Leaf Rapitest Mini pH Tester 1815, what is the reading when needle is at the black line between 6 & 7? 6.5 or 7?

I see that the PH values are located above the color scale bar between the black lines. Does this mean that each black vertical line is 4, 5, 6, 7, 8? For example, is the black line between 5 and 6 indicating a PH of 6 and then values between 6 and 7 between the lines (yellow)? My reading sits just slightly below the line between the 6 and 7. What is my actually reading? Approximately. Just below a PH of 6.5 or just below 7? Thanks for your help.

Answer:

The Luster Leaf Rapitest Mini pH Tester 1815 does not provide an exact measurements if the reading falls between numbers.  If closer to the 7 that would be between 6.5 - 7, if it was closer to the 6 that would 6 - 6.5.
