If you’re an All-Grain brewer, water pH is crucial for your brew. Having the correct pH in your mash and sparge water helps reduce the chance of off-flavors, improves conversion, and ensures optimal yeast health in the fermentation. But paper test strips can be maddening.

The Checker 1 pH Tester is a simple meter that provides fast & accurate pH measurement.

Easy to recalibrate using the adjustment screws on top of the unit body.

We recommend both 4.01 and 7.01 buffer solutions for recalibration and storage solution to prolong the life of the electrode.
