This desiccant assembly refill kit is compatible with the Complete Desiccant Assembly for the Kaymont Model 2000, GEO Calibration Model 2000SP, Model 2000SHR and Model 1000SP.

Model 20000 Series humidity generators use a W A HAMMOND DRIERITE CO 27068 L68GP 300 L/hr, 100 psi Gas Purifier. Half of the polycarbonate column is filled with 250 mL of indicating Drierite producing a terminal dryness of 0.005 mg/liter. The other half contains 250 mL of 5A molecular sieves for removal of trace impurities. Total capacity is 500 mL.  A 40-µm, 316 stainless steel outlet screen assembly prevents particulate migration. Upon reaching saturation, the Drierite column will change in color from blue to pink, indicating that the Drierite must be regenerated, or a refill kit should be used.
