Levosil offers cobalt-free humidity indicators with color changes.
Since 1998, Levosil has been manufacturing cobalt-free brown humidity indicators, ensuring 100% cobalt-free products.
Our humidity indicators consist of a card saturated with a chemical substance that transitions from brown to teal blue upon reaching specific relative humidity levels (e.g., 30%, 40%, 50%).
Levosil’s brown cobalt-free humidity indicators adhere to Jedec 0033 standards. In addition to cobalt-free humidity indicators, Levosil S.p.A. also offers cobalt dichloride-free options, with a color change from blue to pink.
