Buffer Powders(4.00/6.86/9.18)

Product detailed description

To ensure your pH meter remains highly accurate, regular calibration with our three buffer solutions is essential. If you haven't used your pH meter in some time, we highly recommend using a buffer solution before starting your brewing process. For optimal care, use a storage solution after every use if you don’t already have one.

Includes:

• Calibration powder 4.00
• Calibration powder 6.86
• Calibration powder 9.18

Instructions:

1. Pour the entire powder packet into a clean 250mL glass beaker.
2. Add 250mL of deionized water to the beaker.
3. Stir until the powder is fully dissolved.

The pH solution provides accuracy within ±0.01 pH.
