humidity indicator sticker

Brief

Humidity indicator card is a kind of accurate and convenient humidity testing means, through the color change of the indicting dots on the card.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.

• The humidity indicator dots will change from brown 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

Brief

Humidity Indicator Card (HIC) is a convenient and cheap method to check the humidity. We can judge the humidity inside the packing from the color changed. Each card marked the warning when the color has changed, then the package should be replaces the new desiccant.

All HICs meet the requirements of RoHS, CTI and SGS test, MIL-I-8835A, JEDEG and GJB2494-95 standard.

Storage

• Store humidity indicator cards in original sealed iron can. Immediately seal the can after every opening. The dot color shows blue before usage
• Store in dry, cool area and keep them out of direct sunlight and away from water
• Usually packed with small sachet silica gel desiccant,which prevent the HICs lost function before usage.

Brief
Humidity indicator card (also know as HIC, humidity indicator card, moisture indicator)is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded. 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, such as PCB, IC, LED, especially military and semiconductor. 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.

One dot 30% Blue to Pink humidity indicator card for Preservation Package

Brief

Humidity indicator card is a kind of accurate and convenient humidity testing means,through the color change of the indicating dots on the card.

Easy to clearly observe the relative humidity inside the current packaging

Cobalt Dichloride free series,Cobalt free series,Cobalt and Halogen free series humidity indicator,which can meet the needs of humidity indication on different occasions and under different environment.

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.

Brief

Humidity Indicator Cards (HICs) provide a low cost method of indicating humidity conditions inside a moisture barrier bag after vacuum packaging. The indicator spots on the HICs change color from blue to pink as humidity increases and from pink to blue as humidity decreases.

This is color reversible humidity indicator card that meets the requirements of military specifications MIL-1-8335 and MIL-P-116 method ii.
