* At certain percentage relative humidity (%RH), absolute humidity (μg/cm3) varies significantly with temperature and accordingly the indicator response time. For example, at 50% RH and 10oC, absolute humidity is 4.7μg/cm3. Accordingly, it takes the indicator 46 minutes to show noticeable color change, whereas at 50% RH and 35oC, absolute humidity is 19.7μg/cm3. Accordingly, it takes the indicator 10 minutes to show noticeable color change.
