The pH Meter ​
​​​​​​​pH is a fundamental property of any solution, so it should therefore come as little surprise that a pH meter is an indispensable instrument for ensuring quality beer. pH is an important component of virtually ever step​ of the brewing process, including brewing water, mash, sparge, wort, beer and packaged product.
​Generally Speaking, pH meters break down into two types - handheld and benchtop. Handheld pH meters may have either an external probe, connected via a cord, or an internal probe. Benchtop meters, as the name suggests, are less mobile but may offer increased precision, increased longevity, and greater e​​ase in probe replacement.
​As with most things, you get what you pay for in a pH meter, but with the proper storage and regular calibrations an inexpensive handheld pH meter should properly function through hundreds of batches.
