humidity indicator cards 10-60% 6 spot (25 cards)

Description :

Humidity Indicator Cards Our Humidity Indicator Cards are specifically designed to alert users when relative humidity exceeds certain levels. These cards are commonly used in electronic components, electronic displays, automotive electronics, and more. We offer these cards in bulk at highly competitive rates, making them an excellent choice for various industrial applications. Product Details: Color Changing Humidity Indicator Cards (20 Pack): Premium cards that are reusable more than 20 times. 6 Dot Indicators: These cards feature six dots indicating relative humidity levels at 10%, 20%, 30%, 40%, 50%, and 60%. Color Change Mechanism: The chemically impregnated spots change from blue (DRY) to pink (HUMID) as humidity increases. Usage Precautions: Do not allow direct contact with foods or medications to be consumed. Calibration: Upon initial exposure to air, all dots may change color due to sudden humidity exposure. Wait about 30 minutes for the card to calibrate to provide an accurate reading. How to Read the Card: If the 10% dot is pink and the 30% dot is blue, and the 20% dot is lavender, the humidity level is approximately 15%. If the 30% dot turns pink, it's time to change the desiccant. The card is reusable; the dots will revert to blue when the humidity level drops. Over time, the color intensity of the dots may fade, indicating that it's time to replace the card. More About Humidity Indicator Cards: A Humidity Indicator Card (HIC) is an economical way to measure relative humidity levels inside sealed packaging. These cards are especially useful in the military and semiconductor industries. The most common HICs change color from blue (less than the indicated RH level) to pink (greater than the indicated RH level). HICs are also found in small electronic devices, such as cell phones and laptops, to alert manufacturers to high moisture exposure. These cards help monitor desiccant activity and are ideal for any application where moisture control is critical. Benefits: Ease of Use: Simple and quick monitoring of humidity levels. Wide Range: Available with indicating materials that change color at various relative humidity levels (10% to 60%). Accuracy: Provides permanent accuracy to ±5% of relative humidity due to a calibrated sensitive indicating element. Versatility: Suitable for various types of barrier packaging. Cost-Effective: Low cost and reusable, offering excellent value. Visual Verification: Allows instant visual confirmation of product integrity. Military Grade: Approved for MIL-I-8835 applications. Applications: Electronic Components Electronic Displays Automotive Electronics Industrial Electronics Computer Hardware Medical Electronics Consumer Electronics Military and Aerospace Electronics Our Humidity Indicator Cards provide a reliable, cost-effective solution for monitoring moisture levels in sensitive applications, ensuring the integrity and longevity of your products.
