To ensure dehydration measures work, Humidity Indicator Cards (HICs) measure the relative humidity inside sealed packages to allow immediate visual inspection of whether it has sustained unsafe humidity levels. Wiitech has developed cobalt-free HIC for the use in the European Member States. Wiitech cobalt-free HIC is a non-toxic, non-hazardous, and environmentally friendly HIC. Moisture sensitive spots respond to various levels of humidity with a visible color change from Green(dry) to Violet (wet). Product WT60C-CF 04. packing material Part
