Is a better PH test needed?

I just researched this. Apparently this kit is the best without spending $100s of dollars. You're probably having a hard time matching the colors, me too!
What you need to do is use more or less drops, or more or less water. I played with this today and found less drops (4) would make the colors match up better.

A titration test would be better, but anything more accurate is very expensive.
Fortunately with pH, and pools in general, close is close enough.

A better pH test is digital and begins around $100 and needs continual calibration. The pH test in the TF-100 combines practicality with decent precision and a good price.
If you tested for as a profession, a digital tester starts to make sense.

There is a cheap better way. You can buy the acid demand regent ( which costs about three dollars) and add a drop to the ph test of the tft100. The drop will lower the PH and usually the color is much easier to read. I usually add a drop or two until the color turns orange and I can read it as 7.5. I find that a PH of 7.5 is much easier to read. Based on the number of drops that it takes to lower it to 7.5, I can use Pool Math to reverse engineer what my initial PH was. I don't think TFT sells that acid demand regent but they should.
An absolute founding tenant of TFP is to make pool management simple and keep it simple. Over the years we have learned that the pH test, while rudimentary, works. That's it....it works.
If it ain't broke......
What duraleigh saidSpeaking of if it ain't broke.
Is it really possible my pH can just stay at 7.6 for weeks even with lots of playtime?
it has.

My Ph stays stable when my TA is 110. I may have to tweak it twice throughout the season.
Go out into natural sunlight to match the colors. If you try to match them up under fluorescents it distorts the colors.
Sure, lots of folks have stable PH. Some say they haven't added acid in years. I am not one of those. 
It's only because I bought six gallons of MA. Maybe I should buy a plow truck and we can avoid winter.
These posts answered my questions about the K-1000 pH test and my relatively consistent pH readings over weeks of time. Thanks to all.
