Ph meter cal.Fred from Houston,Texas
Hey, all is well.great !
Worked fineMary from NEW jERSEY
Worked fine to calibrate a PH meter.
grampaMitch from USA, NE WA state
Used for making buffer solution for calibrating inexpensive electronic PH measuring instrument... works as expected. Purpose is to keep indoor plants happy since the local water system runs a variable PH of about 7 - 8, whereas the plants are happier with a PH of about 6 - 6.5. My old eyes weren't confident with PH paper's subtle color differences. Good price too!
