  1. Humidity Indicator Cards and Plugs | Bee Chems HumichekTM HIC or Humidity Indicator Cards are widely used to measure humidity level inside a packaged environment. HIC is a card on which a moisture sensitive chemical is impregnated such that it will change colour when the indicated relative humidity https://beechems.com/product/hic/ is exceeded. please visit: Blue to Pink With Cobalt Chloride Brown/Yellow to Azure Cobalt Chloride Free HIC are produced from single to multiple spots like: Single spot ( 8% , 10% are most common) 3 Spot (can be produced in range 10-30% or 30-60% and 5, 10, 20 or 5, 10, 60%) 4 Spot (10-40%, 40-80%) 6 Spot ( 10-60% is the most common) HIC can be produced in custom spot requirements in range 8-90%. Humichek meets the requirements of MIL-I-8835A and related defence and aerospace packaging norms.

  2. Plug Type Humidity Indicators While card type HIC find use in small flexible packaging like poly bags, foil packs, cartons etc. Plug type HI are used in rigid packaging like boxes, wooden packs, steel cage packaging etc. They are made mostly from aluminium or stainless steel. These help in knowing the approximate humidity inside the packaging without the need of opening the container. The plugs are tightened into the rigid packaging wall. The clear disc has a humidity indicating strip which indicates the humidity inside. The colour changes as the humidity changes. Our Humidity indicator cards comply with the requirements of standards like EIA 583, J-STD-033, JSTD-033B MIl-P-116, and AS26860 aerospace specifications. The plugs are available with different humidity ranges as: Single spot 3 spot 4 spot It is an inexpensive and easy to use way to ascertain humidity levels inside sealed packing. HIC are impregnated with a chemical solution which changes colour with humidity. These cards are not precision indicators. However, they are good at telling the maximum possible humidity in a package.

  3. For example, if all of the dots are deep blue on a 6 spot card which is a 10-60% card, then it means that the humidity in that container is below 10%.

Change in colour is an indication that desiccant inside the package needs to be changed.
