The originator of the colour change humidity indicator card, Following the most rigorous quality standards, including strict colour meter testing, CW's humidity indicator cards and humidity indicator plugs are designed to meet standards set forth by military agencies and electronic/semiconductor companies, such as Mil-Spec and JEDEC respectively.
Further, CW offers Maximum humidity indicator cards to the logistics industry, as well as humidity indicators for preservation and commercial applications. Selection includes:
Cobalt-Dichloride Free Humidity Indicator Cards
Cobalt Free Humidity Indicator Cards
Purpose:
With the widest selection of humidity indicator (HI) cards for various industry applications, Indicator Cards provide simple, reliable, visual indication of the relative humidity within a sealed package or sealed environment.
What are they
Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Available in numerous configurations, cards indicate relative humidities as low as 5 per cent and as high as 95 per cent, depending on the application and need. There are two main types of humidity indicator cards reversible and irreversible. Reversible humidity indicator cards work much like a thermometer, fluctuating to indicate the current relative humidity level. Maximum, or irreversible, cards are designed to indicate the highest relative humidity level to which goods have been exposed.
Why use them:
High relative humidity levels can cause irreparable damage to sensitive equipment, supplies, products and cargo.
Benefits:
Cobalt-Dichloride Free Humidity Indicator Cards:
Cobalt Dichloride Free Humidity Indicator Cards are free of Cobalt-Dichloride (CoCl2), a chemical which has classification and labelling requirements under the European Chemical Agency (ECHA) REACH directives
Fully compliant with JEDEC standard J-STD-033 for colour-change accuracy
Meets all relevant ECB/REACH labelling requirements
Typical applications include the dry packaging of semiconductor and electronic devices
Cobalt Free Humidity Indicator Cards:
Cobalt Free Humidity Indicator Cards are free of Cobalt, a chemical which has classification and labelling requirements under the European Chemical Agency (ECHA) REACH directives
Meets all relevant ECB/REACH labelling requirements
