The W.A. Hammond Drierite Co. indicating drierite can be regenerated for repeated use and contains cobalt chloride.
The W.A. Hammond Drierite Co. indicating drierite appears blue when dry and changes to pink when it absorbs moisture. This color change is pronounced and clearly visible. The procedure makes it valuable when it is necessary to know with certainty that dryness is being maintained and to signal when the drying agent should be replaced. It has the same efficiency as regular Drierite, and somewhat of greater capacity due to the desiccating effect of the cobalt chloride. Containing 97% CaS04, 3% CoCl2, this package includes 5 Ibs. bottle is sold individually.
