On a daily basis, before making measurements with the Aqua Fluor
®
, use the solid
secondary standard to verify the Aqua Fluor
®
calibration. If the secondary standard value
has changed by more than ± 5% of its assigned value, the Aqua Fluor
®
should be
recalibrated.
NOTE: Recalibration with a primary standard if possible is recommended.
