Humidity Indicators
Semiconductor- / electronic- / electrical -equipment and their parts, to a certain extent, might be damaged under high humidity. The TANATT® humidity indicator card is a product for checking the environment i.e. the relative humidity of a sealed package for being kept within a safe range. The humidity indicator card can be used to measure the relative humidity of a sealed package easily. The user can estimate the ambient humidity of the package as well as the condition of the desiccant according to the color shown on the card. When the indicating point turns into purple (between blue and pink), the value of the indicating point on the card can be considered as the current ambient humidity. If the humidity in the package is high, the indicating point on the card will turn into pink from blue. Your products can be prevented from being exposed to moisture after this humidity card is used.
