Buffer Solution Powder for Beverage Doctor

Doc's Cellar

  • $3.99

Use buffer solutions to keep your pH meter calibrated. These are the same 3 solution powders that are included with the Beverage Doctor pen-style pH meter.   We would strongly recommend if you haven't used your Beverage Doctor in a while to always use a buffer solution before you start your brew.

  • Completely empty the powder into a clean 250mL glass beaker
  • Add 250mL of deinoized water to the beaker
  • Stir until the powder has completely dissolved
