pH meters must be regularly 'calibrated' (i.e. adjusted for accuracy) using standard pH buffer solutions which are made to an internationally agreed recipe.
- Flairform's buffers are formulated with NIST specified ingredients.
- Stabilised to resist algae or growth formation: Growths' can contaminate pH electrodes which in turn affects the “slope” value beyond the software’s ability to compensate.
