6dolts pcb packing humidity indicator card


Humidity indicator cards are impregnated with a solution of cobalt chloride that has been carefully mixed to change color from blue through various shades of magenta - red, to a pink. These cards are not precision indicators. However, they are very good at telling you the maximum possible humidity in a container. For example if all of the dots are deep blue on a card which is a 10%- 60% card than you can be assured that the humidity in that container is below 10%. This is very important for some products and household items because as long as the humidity is below 40%, basic corrosion (rust) will not occur. Neither will mildew or mold in clothing or paper products. Finally, all sophisticated electronics: video cameras, computers, SLR cameras, sophisticated instruments etc. enjoy a much longer and more reliable life if they are maintained at a very low relative humidity.
