A pH Meter is not only considered by some an essential tool for all grain and commercial brewing, but is also a very useful tool to have for making sour beer.

Recommend pH Meters

High End pH Meters

(To do)

Budget pH Meters

pH meters can range from $30 to $500+. The problem with many of the cheaper pH meters is that their reliability and longevity are often questionable [1]. Commonly, two pH meters are recommended by by trustworthy sources (AJ Delange and Kai Troester).

Hach Pocket Pro+ pH Tester with Replaceable Sensor.

Hach Pocket Pro+

Features:

  • This pH meter is recommended by AJ Delange [1][2].
  • Does not require storage solution (there is an o-ring seal on the cap, which only needs to have a few drops of distilled water in it).
  • Replaceable sensor.
  • Stability [1].
  • 2 Buffer calibration.
  • Electrode longevity [1].
  • Junction resistant to fouling by sugars, proteins [1].
  • Lets the user decide when to accept a buffer calibration reading [1].
  • ATC [1].
  • Automatic buffer recognition [1].

Disadvantages:

  • Despite having an automatic calibration message, this pH still often needs to be calibrated before each use [1].

Milwaukee MW102 pH/Temp Meter (formerly SM101 and MW101).

Milwaukee MW102

Features:

  • This pH meter is recommended by Kai Troester (SM101 originally) [3].
  • 2 Buffer calibration.
  • ATC.
  • Stability [4].

Disadvantages:

Buffer Solution

Buffer solution will be required to calibrate a pH meter. In general, it is recommended that a pH meter have a 2 point calibration method, which requires 4.0 buffer solution and 7.0 buffer solution. Many buffer solutions for pH meter calibration can be found on Amazon or other retailers.
