Cobalt-Free 10%,20%,30% humidity indicator card from Brown to Green for paper historic relic in 3 dots

Brief

Humidity Indicator Card (HIC) is a kind of visible card with several dots that can change the color from "Dry" to "Wet", each dot on the card indicates one specified relative humidity degree.
The dot color will change along with the RH degree from blue to pink (common cobalt-containing HIC) or brown to azure (cobalt-free HIC). It can help the users to know the inside humidity condition and decide whether the desiccant should be replaced or not.
It's so easy to monitor the interior humidity conditions of the package that can prevent the goods from moisture damage

Humidity indicator card (also know as HIC, humidity indicator card, moisture indicator) can easily measure the relative humidity inside the sealed package to allow a quick and low cost inspection of whether the humidity level is safe.

The colour of indicator dot turns, meaning that RH in the package has or had been reached the RH value of that dot. So it is easy for us to estimate the validity of desiccant so as to change desiccant in time. At present, humidity indicator cards are more and more applied in packages of electronics and optical components, which are sensitive to humidity, effectively improving the quality of products.

This item is an inexpensive way to quantify relative humidity levels inside sealed packaging. They are available in many configurations and used in many applications, especially military and semiconductor.

• The humidity indicator dots will change from yellow to green as the relative humidity increases in the volume of air surrounding the indicator
• The humidity indicator dots are reversible, and the yellow dots will change back to pink when the volume of the air is dried
• The humidity indicator shows the most accurate value when the temperature is 23°C
