Also a small tip…after kicking a keg.

I clean the keg with hot water then it gets a hot PBW soak overnight. The keg then gets another hot rinse and a quart of starsan solution shaken up inside. I then purge the keg completely with CO₂… pulling the pressure relief valve multiple times to evacuate O₂. I store the keg pressurized with CO₂ until it’s ready to be filled. When ready to fill I just release the pressure and rack the beer into the CO₂ filled keg.

I’d say as a minumum look for

  1. Precision 0.01 (means you can read it to 0.01 – not that it is accurate to 0.01)

  2. Accuracy better than or equal to 0.05. A meter capable of 0.02 is better as the accuracy of your readings is then set by the buffers and not the meter itself.

  3. ATC

  4. Ability to calibrate to 2 buffers (I understand there are some units out there that only allow 1 buffer calibration).

  5. Under “nice to have” and as you can get it in under $100 meters I’ll list it: Automatic buffer recognition

pH Meter: How long to get a reading?

One thing I wasn’t expecting is that it takes about 2-3 minutes to get an accurate reading.  When I first insert the probe, the initial reading is usually around 7 or 8, and then it slowly starts going down until it eventually settles at the final reading.  I have found that gently stirring the probe in the sample speeds the process up a bit and actually seems necessary to get an accurate reading (as confirmed with testing solutions).
