pH Test Strips Beer Range
Economy pH test papers. 100 strips per vial, range 4.6 to 6.2. The perfect range to measure both your mash and sparge water pH in all-grain brewing.
The range is too small, need at least 4 more points to figure out in what acid level is the beer.
I was disappointed, due to the strips not going low enough to check the pH for a sour.
I found these to be totally inaccurate and decided on upgrading to a digital ph testing kit.
Completely useless for actually testing mash PH...
I like how easy they are to use and you don't have to calibrate them at all. I wish it was a lot tighter on the pH reads instead of 5.0 or 5.4. There is no color in middle for exact. It is good for getting pretty close though.
