humidity indicating cards

Blue to Pink One dot 50% Humidity Indicator Card for Optical Components

Introduction

Humidity Indicator Card (HIC) is a kind of visible card with several dots that can change the color from "Dry" to "Wet", each dot on the card indicates one specified relative humidity degree.
The dot color will change along with the RH degree from blue to pink (common cobalt-containing HIC) or brown to azure (cobalt-free HIC). It can help the users to know the inside humidity condition and decide whether the desiccant should be replaced or not.
It's so easy to monitor the interior humidity conditions of the package that can prevent the goods from moisture damage

Introduction

Humidity Indicator Card (HIC) is a kind of visible card with several dots that can change the color from"Dry" to "Wet", each dot on the card indicates one specified relative humidity degree.
The dot color will change along with the RH degree from blue to pink (common cobalt-containing HIC) or brown to azure (cobalt-free HIC). It can help the users to know the inside humidity condition and decide whether the desiccant should be replaced or not.
It's so easy to monitor the interior humidity conditions of the package that can prevent the goods from moisture damage.

Storage
a) Please store in a dry and cool environment,avoid direct sunlight and water.
b) Please replace the desiccant when open the packaging more than three times
c) Usually packed with small sachet silica gel desiccant,which prevent the HICs lost function before usage.

Features

1. The quick and low cost method quantify relative humidity levels inside sealed packaging.
2. Printed with moisture sensitive spots which respond to various levels of humidity with a visible colour change.
3. Support the visual proof of the relative humidity level within given environment.
4. Visibly monitor the interior humidity conditions of the package.
5. Easily judge whether your desiccant works well or need to replace inside a sealed package or closed space.
6. Available in numerous configurations.
7. All the HICs meet MIL-I-8835A requirements
8. Constantly indicate relative humidity as low as 10% and as high as 60%,depending on the applications and requirements.

Description

Blue to Pink one dot 50% Humidity Indicator Card for Optical Components

Brief

Humidity indicator card (also know as HIC, humidity sensitive card, moisture indicator) is the card which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded.

This item is an inexpensive way to quantify relative humidity levels inside sealed packaging. They are available in many configurations and used in many applications, such as PCV,IC,LED,especially military and semiconductor.

Features

1. Lead-free, DMF free, RoHS compliant.
2. High accurate, tolerance is ±5%.
3. Reversible color change.
4. OEM allowed
5. Cobalt-Free and Halogen-Free are available
6. All the HICs meet MIL-I-8835A and J-STD-033 requirements
7. A permanent after-sales service

Brief

Humidity indicator card is a kind of accurate and convenient humidity testing means, through the color change of the indicting dots on the card.The colour of indicator dot turns, meaning that RH in the package has or had been reached the RH value of that dot. So it is easy for us to estimate the validity of desiccant so as to change desiccant in time. At present, humidity indicator cards are more and more applied in packages of electronics and optical components, which are sensitive to humidity, effectively improving the quality of products.

• The humidity indicator dots will change from brown to green as the relative humidity increases in the volume of air surrounding the indicator
• The humidity indicator dots are reversible, and the yellow dots will change back to pink when the volume of the air is dried
• The humidity indicator shows the most accurate value when the temperature is 23°C
