4HIC100

The 4HIC100 is a 4-spot Humidity Indicator Card designed for dry packaging surface mount devices. Monitors the most critical humidity range for SMD's. Colour reference bar assists with accurate readings. Blotting paper impregnated with cobaltous chloride card. Humidity indicator cards (HICs) are printed with moisture sensitive spots which respond to various levels of humidity with a visible colour change from blue to pink. The humidity inside dry packed barrier bags can be monitored by including an HIC inside. When the bag is opened, the card can be examined for proper dryness inside the bag. This indicates that the barrier bag and desiccant functioned correctly.

• Blotting paper impregnated with cobaltous chloride material
• 2 x 3" Card size
• Accuracy based on ambient temperature of 75°F
