Description

Why I need choose your product?

Existing humidity indicator cards found in the market are impregnated with a chemical called cobalt chloride In the dry state, cobalt chloride is blue in color. After absorbing moisture cobalt chloride changes to pink color. A recent amendment made to the European CEE directive 67-548 pertaining to the Classification, Packaging and Labeling of dangerous materials, has classified cobalt chloride as a carcinogenic material. Improper handling of items containing carcinogen may cause health hazards and environment hazards, thus, goods containing cobalt chloride will not meet EU standards.
Our new range of humidity indicator cards are carcinogen-free and meet EU standards and color change can be blue to pink, yellow to azure, blown to green.
