Reversible 3 Dots Humidity Indicating Cards Blotting Paper Ingredient For Bulk Packaging

3 dots Blue to Pink 10%-30% humidity indicator card for Bulk Packaging

Brief

Humidity indicator card provides a low cost method of indicating humidity conditions inside a moisture harrier bag after vacuum packaging.The indicator spots on the HICs change color from blue to pink as humidity increases and from pink to blue as humidity decreases.

Humidity indicator card (also know as HIC, humidity indicator card, moisture indicator) can easily measure the relative humidity inside the sealed package to allow a quick and low cost inspection of whether the humidity level is safe. 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.

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, especially military and semiconductor.

Specification&Packing

Features

This is a colorchange reversible humidity indicator card that meets the requirements of military specifications mil-1-8335 and mil-p-116 method ii.this indicator card has 6 indicating spots10/20/30/40/50/60-percent rh, they change from blue dry to pink humid. A great tool to assist you in keeping your valuables protected.

Support the visual proof of the relative humidity level within given environment.It is easily judge whether your desiccant works well or need to replace inside a sealed package or closed space.

• The humidity indicator dots will change from blue to pink 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

Storage

• Store humidity indicator cards in original sealed iron can. Immediately seal the can after every opening. The dot color shows blue before usage
• Store in dry, cool area and keep them out of direct sunlight and away from water
• Usually packed with small sachet silica gel desiccant,which prevent the HICs lost function before usage.
