This humidity indicator card is a reversible color-change indicator.  As the humidity increases, the chemically impregnated spots change from a blue color (DRY) through a lavender, to a pink color (HUMID).  As the humidity level decreases, the spots change from a pink color (HUMID), through a lavender, back to a blue color (DRY).  Cards are packed in re-sealable containers with desiccant for an extended shelf life.  Each of these cards are accurate to ±5% relative humidity at 75°F (24°C).  Other varieties are also available, some incorporate temperature indicators.  Most can be printed with your company's special copy.
