Humidity Indicator Cards & Plugs

Humidity Indicator Cards (HIC) are used to monitor level of relative humidity (RH) inside the packaging they are applied.

With the help of a moisture-sensitive impregnated chemical, they change color when the specified RH is exceeded. Depending on the application, they can be used to indicate RH levels from 5% to 95%.

Reversible HIC spots continue to change color as the moisture levels change. While Irreversible (also called ‘Maximum Indicator Cards') HIC indicate the highest RH level goods inside the pack have been exposed to.

Why to use Humidity Indicator Cards & Plugs? 

High humidity levels may seriously damage some sensitive materials (electronic goods and alike) and goods. Shippers usually apply dry-packaging and place desiccants when shipping such products through the supply chain. However, sometimes it is difficult to detect whether the products were safely protected by the desiccant which might have reached its adsorption capacity earlier than expected. 

Although humidity indicator cards do not indicate the level of humidity precisely they offer a good and and a economical solution to detect the moisture content of a closed package. Users can check the RH levels and see if their products are damaged by moisture impact. They can determine whether they need to replace the desiccant inside the packaging.


Humidity indicator cards are available with different options such as : 

* RH spots : 5-10-15 %, 5-10-60 %, 30-40-50 %, 10-20-30-40 %, 10-20-30-40-50-60 %

* Types : Cobalt Dichloride, Cobalt Dichloride Free, Cobalt Free
Color Change options:  from blue to pink, from brown to green, red to yellow, yellow to green

Humidity Indicator Plugs allow users to monitor humidity levels inside a closed package without the need to open it.

There are options of brass, aluminium or stainless steel plugs.

They are mounted on the sealed packaging like a window with a moisture indicator card installed. They provide a visiual indication of humidity levels inside the packaging.

Desiccator Plugs not only indicate humidity levels inside the sealed container but also control it by the help of a desiccant tube. They are usually designed for small packages with limited space.

Why to use humidity indicator plugs ?

Sensitive products often shipped and stored in sealed packaging which can not be opened in transit. By humidity indicator plugs users are able to easily check humidity levels and ensure goods are safely kept under reasonable relative humidity.
