Humidity Indicator are designed for mounting in moisture sensitive electronic or electro-optic equipment, or any other humidity controlled enclosure. They readily detect changes in the humidity of the space being monitored by using a colour change indicator paper which turns from blue to pink as the humidity increases, and turns back to blue when the humidity decreases. The indicator solution used is water soluble and therefore humidity indicator papers should not be placed in direct contact with water or steam or exposed to extremely high humidity's for protracted periods of time. Also strong solvents such as ammonia fumes will cause the bleaching of the colour change dye and lose colour reversibility.

Most of these indicators can be fitted with a desiccant cartridge which will adsorb any moisture entering the equipment during its use. These are known as static desiccators.



EnviroTronics are the exclusive Distributors for Desiccare, Inc., manufactures a full line of Humidity Indicator Cards (HIC) which allows a low cost method of indicating humidity conditions for various types of barrier packaging, including MIL Spec (MIL-I-8835) applications. The 30%, 40%, 50% HIC cards complies with MS 20003-2 and the 5%, 10%, 15% complies with JEDEC Standard 033. The 5%, 10%, 60% card complies with JEDEC Standard 033B.

Standard Humidity Ranges are as follows:

1.  - 8%
2.  - 5%, 10%, 15%
3.  - 10%, 20%, 30%
4  -  10%, 20%, 30%, 40%
5.  - 20%, 30%, 40%
6.  - 30%, 40%, 50%
7  -  10%, 20%, 30%, 40% 50%, 60%
8.  - 5%, 10%, 20%, 30%, 40%, 50%, 60%
Desiccare’s Humidity Indicating Cards are the most accurate cards available in the
market today. They are often used in conjunction with a desiccant and a moisture
barrier bag when shipping electronic components.
Benefits of using a Humidity Indicator card:

1. Indicate humidity conditions in various types of barrier packaging
2. Often used in conjunction with a desiccant
3. Allow instant visual verification of product integrity
4. Approved for MIL – I – 8835 applications
5. Low cost
6. Spots turn fr om blue to pink to indicate humidity levels


Moisture is the worst thing that can affect electronics by damaging the way they function or lead to some irreversible glitches in electronic components. Moisture also leads to other problems such as rust and accumulation of dust, which can affect the performance of any electronic items.
While the problem is serious, the solution is rather simple - placing a desiccant with your electronics will protect your products against moisture. There are some crucial electronic items, such as, semiconductors, circuit board and several other photo-electronic components that are vulnerable to moisture. Keeping electronic items away from humidity and moisture can help increase their life span. Use Desiccare’s Humidity Indicating Cards to accurately quantify relative humidity levels and help protect your products against moisture problems.
