Overview of humidity indicator
Nicepak manufactures a full line of Humidity Indicator Cards (HIC) which allows a low cost method of indicating humidity conditions for various types of barrier packaging, including MIL Spec (MIL-I-8835) applications. The 30%, 40%, 50% HIC cards complies with MS 20003-2. The 60% card complies with JEDEC Standard 033D. Cobalt dichloride free and cobalt free options that meet EU Reach requirements are available - Contact Us for information.
Moisture is the worst thing that can affect electronics - it can damage the way they function or lead to irreversible glitches in electronic components. Moisture also leads to other problems such as rust and accumulation of dust, which can affect the performance of electronic items.
While the problem is serious, the solution is rather simple: placing a desiccant with your electronics will protect your products against moisture. There are some crucial electronic items that are vulnerable to moisture. Keeping electronic items away from humidity and moisture can help increase their life span. Use Nicepak's humidity indicating cards to accurately quantify relative humidity levels and help protect your products against moisture problems.

(1) Reversibility of change of color: According to the presence or absence of oxygen in the container, the color of the oxygen indicator can change reversibly from blue to red and from red to blue for many times.
(2) Reaction time for change of color: When the oxygen indicator is used in combination with oxygen scavenger, the oxygen indicator turns red within 4 hours after the oxygen concentration drop to 0.1%. When oxygen enters from outside, the oxygen indicator will turn blue within 30 minutes. (Situation at 25ºC)
(3) Indicating the range of oxygen concentration: When the oxygen concentration in the sealed container is less than 0.1%, the oxygen indicator is red; When the oxygen concentration in the sealed container is less than 0.5%, the oxygen indicator is blue;
Indicate humidity & O2 conditions in various types of barrier packaging
Can be used in conjunction with a desiccant for full effect
Instant visual verification of product integrity
Approved for MIL-I-8835 applications
Low cost
Easy to use (spots turn from blue to pink to indicate humidity levels)
PCB's should be vacuum packed in a width adequate desiccant and humidity indicator card.
1:Please store in a dry and cool environment, avoid direct sunlight and water.
2:Inner packing: Sealed vacuum bag+ tinplate can, outer packing: Cartons and pallets.
3:When open the packaging more than three times, please replace the desiccant.
4:Put one desiccant bag along with the HIC card inside the vacuum bag and get sealed.
