Can I confirm that the ‘standards’ simply test the colorimeter?
Can it be calibrated with the standard or does it just tell you whether the colorimeter is working correctly?
Annoyingly the standard for the dkh Alk checker is more expensive than the others. I wonder if there’s a technical reason for that or just due to demand.
