I'm not a big fan of "matching" the color of the mix with the scale on the measuring tool. I feel like as you move it and adjust the lighting it changes. Is there a drop based pH test available that either has a more dramatic color change than the small Taylor kit in the TF100 package, or a different method altogether?
Is something like this any good?
