In the form of spherical or irregularly-shaped grains, the gel is currently presented purple, orange or yellow.
Characteristics
Color-Variable Silica Gel
1 In the form of spherical or irregularly-shaped grains, the gel is currently presented purple, orange or yellow.
2 With silicon dioxide as the chief ingredient, the product performs all the functions of blue silica gel but does not contain cobalt chloride and is therefore innocuous and pollution-free,
3 Its color varies as humidity changes.
Use:Mainly for drying and indicating humidity of precision instruments, medicine, petrol chemicals, foodstuff, clothing, leather.

1. Used for absorbing moisture of instruments, gauges and equipment in the enclosed conditions.
2. After adsorb moisture, it turns blue into red, visually indicating the relative humidity of the given environment..
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moistures and judges the relative humidity of a given environment.
4. Used to judge if the humidity of a environment is up to the specified requirements and to determine if the adsorbent or drier ceases to be effective.
