Beverage Doctor pH Buffer Solution Powder - 3 Pack (4.00/6.86/9.18)

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 (MT624). 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.

Directions:

• Completely empty the powder into a clean glass jar
• Add 8.5 oz of deinoized water
• Stir until the powder has completely dissolved
