Desco Industries, Inc. Anti-Static, ESD, Clean Room Accessories 13854

The product is a Cobalt-free Humidity Indicator Card (HIC), specifically part number 16-13854-ND. This card is designed to measure relative humidity levels within sealed packages, providing a visual indication of moisture exposure that could potentially damage sensitive equipment and materials. The card features humidity-sensitive spots that change color in response to moisture, allowing for immediate assessment of humidity conditions. The HIC is reversible, with color changes occurring from brown (dry) to yellow (humidity condition), and it can revert back to brown when placed in a dry environment with desiccant. It is important to note that the accuracy of the card may be compromised if exposed to relative humidity levels of 60% or greater. The card is packaged in a can and should be stored in a sealed container with desiccant to maintain its effectiveness. This product meets the requirements of MIL-I-8835 and IPC/JEDEC J-STD-033D (Type 1), making it suitable for use in environments where moisture control is critical.
