The MS20003-2 Humidity Indicator Card (Clariant Part Number 24878527694) is a military-grade, multi-spot humidity indicator designed to verify moisture levels inside sealed packaging systems. Featuring 30%, 40%, and 50% RH indicator spots, this card offers fast, reversible, and highly accurate visual confirmation of internal humidity—making it essential for Method II packaging, desiccant systems, barrier bags, and electronics preservation.

Manufactured in accordance with MIL-I-8835 testing requirements, the MS20003-2 humidity indicator card provides ±2.5% RH accuracy and a dependable color-change response used widely across defense, aerospace, electronics, and industrial packaging applications. Each indicator spot transitions from blue (dry) to pink (humid), enabling technicians to quickly determine whether stored products remain within acceptable moisture levels.

This card is approved for Method II packaging, making it suitable for use inside watervaporproof barrier bags including MIL-PRF-131 laminates, desiccant-controlled packaging, and other moisture-sensitive military preservation systems.
