Humidity Indicator Card

Impact Indicator label is a self-adhesive and irreversible device that can be attached to a package to deter mishandling and reduce damage-related costs by indicating when products have been exposed to a potentially damaging impact during transit or in storage.

These labels are tamperproof, mechanically activated devices that turn bright red when an impact occurs.

Overview

The humidity card (or humidity display card, humidity indicator card, HIC) is a card used to display the humidity status of the sealed space. The percentage data above or to the side of the circle is the relative humidity data indicated by the corresponding circle.Humidity indicator card is a device on which a moisture-sensitive chemical is impregnated such that it will color change when the indicated relative humidity thresholds exceeded.

Humidity indicator card is a device on which a moisture-sensitive chemical is impregnated such that it will color change when the indicated relative humidity thresholds exceeded. This has usually been of two types, a blotting paper impregnated with cobalt(II) chloride base and color change blue to pink when RH threshold exceeded; the other is cobalt-free chloride base and color change brown to blue when threshold exceeded. The spots on the humidity indicator card change color to indicate the humidity in a given cargo or environment, allowing workers to monitor humidity at a glance and inspect cargo if humidity exceeds safe levels.

Humidity indicator is a cost-effective way to detect and indicate relative humidity levels. They are available in many configurations and used in many applications which sensitive in humidity conditions, especially food, chemicals, military, semiconductor, etc.

Instruction

When the humidity of the environment reaches or when the indicator point on the humidity indicator card shows a value, the
indicator point will change from dry color to hygroscopic color.
When the humidity of the environment decreases, the color of the dots on the indicator card will change from hygroscopic color to dry
color again.
When the color of the indicated point changes to the specified color, the value in the point is the humidity value of the current environment.
