Humidity instruct card
Securtiy/Insecurtiy Indicating Card:The dot in the card will show different color along with the change of RH of enviornment moisture. Comparing the color of dot with the standard color plate on the indicating card, the blue dot shows the relative humidity is securtiy, but the pink dot shows the relative humidity is insecurtiy, so you need to change the desiccant to avoid the mould of goods.
íí Three colors point out the card : The dot in the card is become pink with the change of the environmental relative humidity RH value bluly gradually separately, each dot show relative humidity RH value 5%-15%- 10%-20% or 30%-50% one humidity value separately, can show the level of the relative humidity accurately , in order to help to confirm whether the drier is changed .
íí Six Color Indicating Card: The dot on the card will be turn pink from blue gradually according to the transformation of RH of relative humidity and every dot indicates the humidity degree of relative humidity from 10%-60%. It can show the hierarchy of relative humidity precisely and help you to ensure whether the desiccant needs to be changed.
