Probably more than I will ever use!
Color: 15 Pack
Using just 3 packets, I have prepared the calibration solution in separate 1/2 pint Mason Jars. Since I am only using it occasionally to recalibrate my pH pen, it will likely be several months before I have to use another set of packets. This set of 15 packets will probably last me 3 years! Great value for the amount you receive! ... show more

Best In Class
If you use as directed, with the correct amount of deionized water, at the close to the right temperature, you can't go wrong. I verify with litmus paper to insure accuracy.
