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.
Features:
- This pH meter is recommended by AJ Delange [1].
- 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).
Features:
- This pH meter is recommended by Kai Troester (SM101 originally) [2].
Disadvantages:
