Cons
Ph papers are much less accurate than ph papers for a narrower part of the ph scale (say 4-8) don't really know. I have no clue if this stuff works. They just keep ripping.
Highlights
Quality
Accurate easy to use very good ph testing strips out of the 2 different ph testing strips i purchased these are the most accura... Read More
Works and has plenty of test paper on each roll
Pull it apart and unwrap the spool inside
I tested the first bit of paper with straight white vinegar vinegar diluted with 50 water and then diluted with 75water
Price
They are very affordable accurate easy to use and read and also are versatile for so many different things
Like the inexpensive way to make sure my treated well water stays at 7 ph
Used to check soil ph was much cheaper than buying the ones marketed for gardening
Shipping
They came on time and each spool was in a cardboard box and then both boxes were placed inside of a sturdy plastic zip lock bag
Packaging/appearance
The color change happens pretty fast and is easy to read and compare to the packaging
No instructions that made any since to me were offered and the one picture did not show that the container was actually a box
Tell you what this is shocking when you open the boxes 4 very tiny reels

It is the negative log of hydronium ion concentration ph logh
Posted by a reviewer on Amazon
Since it is a negative log ion concentration goes up as ph goes down and things get more acidic with lower ph
Posted by a reviewer on Amazon
Since it is a base 10 log scale a one point change in ph will represent a 10 fold change in ion concentration
Posted by a reviewer on Amazon
With ph you can dilute something by 50 and only see a very small change in ph
