FAQs
Is this solution only for Bluelab meters?
No, while optimized for Bluelab devices, it is suitable for use with any pH meter that requires calibration using pH 4.0 buffer solution.
Why do I need pH 4.0 calibration?
This solution is specifically used when testing in acidic conditions where the expected readings are below pH 7.0. It is recommended to use it alongside pH 7.0 solution for a two-point calibration.
Can I reuse a sachet?
No, each sachet is single-use to maintain calibration integrity and prevent contamination.
How should I use and store the solution?
Pour the solution into a clean container, never insert probes directly into the sachet. Always discard unused solution after calibration. Keep the sachets sealed and store them in a cool, dry place to maintain accuracy.
