Indicating Drierite

Absorption progress and exhaustion is visually indicated by this efficient drying agent. Colour changes from blue to rose-red as moisture is absorbed. Blue condition can be regenerated several times. Indicating Drierite may be used at the end of large units of Regular Drierite to show the activity or exhaustion of the Regular Drierite, in addition to full charge use in drying towers, absorption bulbs, U-tubes, etc.
