Cobalt Free Humidity Indicator Strips Six Dots For Calligraphy From Brown To Azure

Cobalt-Free 10%-60% humidity indicator card in 6 dots for calligraphy and painting from brown to azure

Brief

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.

United States Military Specification Mil-I-8835A is the governing specification for a humidity indicator card. The humidity indicator card is also specified for use in GJB2494-95, China Military Standard refers to Mil-I-8835A, which is the standard for Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices, also known generically as semiconductors.

• 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
