Product Description

Product Description:

TOPCOD Humidity Indicator Card (HIC)

     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.To provide a simple, reliable, visual indication of the relative humidity within a sealed package or any given environment.

What are they?

  • Humidity Indicator Cards: A Comprehensive Guide to Monitoring Relative Humidity Levels

  • In the realm of humidity control, Humidity Indicator Cards (HICs) play a vital role in monitoring relative humidity levels. These small, paper instruments come in various configurations, providing accurate indications of relative humidity across a wide range, from as low as 5 percent to as high as 95 percent, catering to diverse applications and needs.

  • Understanding the Types of Humidity Indicator Cards

  • There are two primary types of humidity indicator cards: reversible and irreversible, each serving a specific purpose.

  • Reversible Humidity Indicator Cards: Like a Reliable Thermometer

  • Reversible humidity indicator cards function similarly to a thermometer, offering real-time monitoring of the current relative humidity level. As humidity levels fluctuate, these cards visually reflect the changes, enabling users to gauge the immediate moisture conditions accurately. Reversible HICs are particularly valuable in applications where continuous monitoring of relative humidity is essential.

  • Irreversible or Maximum Humidity Indicator Cards: Capturing High Humidity Exposure

  • In contrast, irreversible humidity indicator cards are designed to record the highest relative humidity levels to which goods have been exposed. Once the humidity reaches a predetermined threshold, the card permanently changes its color, serving as a clear indication of past high humidity exposure. This irreversible change acts as valuable evidence for quality control and insurance purposes, ensuring proper handling and storage of moisture-sensitive goods.

  • Choosing the Right Humidity Indicator Card

  • Selecting the appropriate humidity indicator card depends on the specific requirements of your application. Consider factors such as the desired range of relative humidity, the need for real-time monitoring versus historical exposure documentation, and the desired sensitivity level.

  • Final Thoughts

  • Humidity Indicator Cards offer a straightforward and reliable means of monitoring relative humidity levels. By leveraging reversible and irreversible types, users can effectively assess both real-time and past humidity conditions. Whether it's ensuring the optimal storage of sensitive products or meeting quality control standards, integrating humidity indicator cards into your humidity management strategy is a wise and proactive approach.

Why use them?

     Excessive levels of humidity can cause irreversible harm to delicate equipment, supplies, merchandise, and shipments. While many manufacturers and shippers make efforts to safeguard their goods against moisture damage, such as utilizing desiccants, it can be challenging to determine the effectiveness of these measures. Certain products, like electronic devices, often exhibit no visible signs of moisture damage, and desiccants may reach their saturation point before users realize the need for replacement.

    That's where humidity indicator cards come into play. These cards offer a visual confirmation of the relative humidity levels within a specific environment. If the card indicates elevated humidity levels, users are alerted to replace their desiccant bags and inspect their products for potential damage. By providing this visual proof, humidity indicator cards offer an added layer of assurance in moisture control.
