pH measuring equipment must be cleaned and calibrated regularly to ensure accurate readings; instruments are calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope) using this solution.
Bluelab solutions are manufactured specifically for Bluelab products, NIST certified, and made to a traceable standard to help your Bluelab products last longer and maintain accuracy. To keep solution accurate: avoid cross-contamination, decant into a smaller cup rather than dipping directly from the bottle, discard the sample after use, and store in a cool, dark place with the lid secured tightly, out of reach of children.
