HUMIDITY INDICATOR CARDS The Monitor Card contains chemically impregnated, humidity sensitive, indicating spots that will change color with moisture. The comparison bar is used to determine relative humidity of air. Select the indicating spot that most closely matches the color of the comparison bar. The measured relative humidity is the percentage indicated on the matching spot. The chemical reaction of the indicating spots is completely reversible; the spots will continue to change color as the moisture levels change. Our HICs’ chemistry formula involves a cobalt compound, but no sulfur compounds.
IPC/JEDEC-J-STD-033D |
Application 1. The humidity indicator spots will change from blue (dry condition) to pink (humid condition) as the relative humidity changes in the volume of air surrounding the indicator. 2. Relative humidity is indicated at the lavender color. 3. Indicator spots will change within eight hours of being exposed to a change in relative humidity. 4. The humidity indicator spots are reversible, and the pink spots will change back to blue when the volume of air is dried. Humidity indicator cards with pink or lavender spots can be returned to a blue color by placing indicators in a sealed container with 33 grams (1 unit) of desiccant for four hours. However, J-STD-033D prohibits reusing an HIC if the 60% spot has exceeded its threshold. 5. The highest humidity indicator spot should be blue before being put into use. 6. The humidity indicator will be at its most accurate at a temperature of 23 °C (73 °F). 7. Avoid contact with indicator spots. Wash any irritated areas with clean water.

Handling 1. Store humidity indicators in original sealed container with desiccant when possible before using, verify that indicator spots have not changed color 2. Replace desiccant bag after three openings of container. 3. Store in dry, cool area. 4. Keep indicators out of direct sunlight. 5. Keep humidity indicators away from water or steam. 6. Ammonia gases will damage humidity indicators. Sufficient Information for Safe Use This document has been prepared in order to provide suddicent information for safe use of the product.
