Product Description

We recommend calibrating pH testers weekly for readings you can trust. It's best to keep pH electrodes wet, and manufacturers recommend using Storage Solution to do this. Calibrate pH meters at both 4.01 and 7.01 to give your pen a "slope" reference. This pH 7.01 buffer solution is only one part of keeping your pH tester in good condition.
