Our advanced red silica gel technology represents a breakthrough in humidity indication systems. This innovative color changing desiccant, developed through extensive research based on customer requirements, features a distinctive ruby red initial state that transitions gradually to light orange upon moisture absorption. Unlike traditional moisture indicators, this product is entirely free from cobalt chloride, ensuring complete safety and non-toxicity. When used in combination with molecular sieve products, it provides precise humidity control at lower levels, making it ideal for various industrial and commercial applications requiring accurate moisture monitoring.
The color change is obvious and the adsorption capacity is strong. It has a wide range of uses and can be used in combination with other adsorbents.
