“With
Flairform's analytical solutions, my tools are going an extra week between calibrations!”

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.
Electrode care: Avoid placing electrodes in oily
solutions as they can “coat” the electrode. Further, avoid measuring
(or leaving electrodes for too long) in
harsh chemicals. For
example, highly caustic (e.g. pH Up, silica additives) or concentrated
solutions such as raw nutrient.
