Humidity indicator cards - Cobalt Dichloride Free - 3 spot 5-10-60% - Tin of 125

Humidity Indicator Cards are used to determine whether products have been exposed to moisture and humidty above recommended storage levels. 

This is a great low-cost method of indicating humidity conditions inside a moisture barrier bag following vaccum packaging. 

As the humidity increases or decreases the moisture senstive spots on the cards change colours.

Cobalt Dichloride Free

Cobalt Dichloride is a chemical that changes colour when exposed to changing storage levels of moisture and is commonly used in HIC's for that purpose. Regulated under European Chemical Bureau (ECB) REACH, Cobalt dichloride is a chemical that is identified as a substance of concern for the environment.

Cobalt Dichoride free HIC's provide electronic and semiconductor manufactuers with an IPC/JEDEC-J-STD-0.33 compliant humidity card that is free of Cobalt Dichloride and complies with EU & WEEE directives regarding hazardous substances. 

Key Features:

• Humidity indicators are used to quickly retect moisture and humidity levels in packaging
• Colours change to indicate RH levels inside of the packaging
• Lightweight material 
• Can be vaccumed sealed
• Cost-effective
• Early identification prevents damaged items from entering production
• Identify and/or monitor humidity levels prior to opening inner contents
• HICs conform to IPC/JEDC 033 standard and IEC 61340-5-1 specifications
• Cobalt Dichloride Free cards meet RoHS, REACH and WEE directive regarding hazardous substances
