Humidity Indicator Cards and Plugs

Humidity Indicator Cards and Plugs provide a simple, reliable, visual indication of the relative humidity within a sealed package. High relative humidity levels can cause irreparable damage to sensitive equipment, such as semiconductors and military instruments.

While many manufacturers take the proper steps to protect their products from moisture damage, such as using desiccants and moisture barrier bags, it is important to also ensure that these steps are effective. Some products, such as electronic goods, often show no visual sign of moisture damage in the event of a breach in the dry packaging system.

Humidity Indicator Cards

Humidity Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Humidity Indicator Cards are available in many configurations and can be customized for any number of applications. We offers cards that meet military specifications (Mil-I-8835 and Mil-Std-2073-1D Method 50) and JEDEC standards (J-STD-033A and J-STD-033B), which govern the dry packing of semiconductors.

Humidity Indicator Cards are available in 2 styles:

• Reversible
  • Relative humidities as low as 5 percent and as high as 95 percent
  • work much like a thermometer, fluctuating to indicate the current relative humidity level
  • most common used
• Non-Reversible cards
  • humidity indications range from 30% to 90% relative humidity
  • designed for applications that require monitoring of the maximum relative humidity products have been exposed to
  • cannot be reactivated, so it provides a non-alterable record of the maximum humidity goods or products have been exposed to

Texas Technologies stocks a wide range of humidity indicator cards for many applications which include: Semiconductors, Electronics, Military, and Industrial. Humidity Indicator cards are available in a variety of configurations and indicators, in a wide range of customizable humidity levels.

• One-spot
• Three-spot Reversible Humidity Indicator Cards
• Four-spot Reversible Humidity Indicator Cards
• Six-spot Reversible Humidity Indicator Cards
• Non-Reversible (one-time) Humidity Indicator Cards

Humidity Indicator Plugs

Color change humidity indicator plugs are the solution to a wide range of military and commercial packaging requirements. Mounted through a container wall, the color change plug reliably measures relative humidity levels with accuracy to within 5%.
