$32.34 $29.40

Humidity Indicator Card, 5% 10% 60% Rh, J-Std-033B, 125 Ea

The humidity indicator spots will change from blue (dry condition) to pink (humid condition) as the relative humidity changes in the volume of air surrounding the indicator. Humidity indicator cards can be returned to a blue color by placing indicators in a sealed container with 33 grams (1 unit) of desiccant for four hours.

      “Humidity Indicator Card (HIC) A card on which a moisture-sensitive chemical is applied such that it will make a significant, perceptible change in color (hue), typically from blue (dry) to pink (wet) when the indicated relative humidity is exceeded. The HIC is packed inside the moisture-barrier bag, along with a desiccant, to aid in determining the level of moisture to which the moisture-sensitive devices have been subjected.” [IPC/JEDEC J-STD-033B section 1.5.7]

      HUMIDITY INDICATOR CARDS
      An integral part of a complete moisture barrier packaging assembly is the
      Humidity Indicator Card. High relative humidity can cause significant, possibly
      irreparable damage to sensitive equipment, supplies, and products. To ensure
      dehydration measures work, humidity indicator cards measure the relative
      humidity (RH) inside sealed packages to allow immediate visual inspection of
      whether it has sustained unsafe humidity levels.
      The Monitor Card contains chemically impregnated, humidity sensitive, indicating
      spots that will change color with moisture. The comparison bar is used to
      determine relative humidity of air. Select the indicating spot that most closely
      matches the color of the comparison bar. The measured relative humidity is
      the percentage indicated on the matching spot. The chemical reaction of the
      indicating spots is completely reversible; the spots will continue to change color
      as the moisture levels change.
      Humidity Monitor cards are sold in cans. The 2” x 3” blotting paper cards indicate
      relative humidity. Humidity Indicator Cards should be inserted and sealed within
      an Moisture Barrier Bag with the desiccant packs.

      The 13868, 13869 and 13870 humidity indicator cards meet the requirements of
      MIL-I-8835 and IPC/JEDEC J-STD-033C.

      Application
      1. The humidity indicator spots will change from blue (dry condition) to pink
      (humid condition) as the relative humidity changes in the volume of air
      surrounding the indicator.
      2. Relative humidity is indicated at the lavender color.
      3. Indicator spots will change within eight hours of being exposed to a change in
      relative humidity.
      4. The humidity indicator spots are reversible, and the pink spots will change back to
      blue when the volume of air is dried. Humidity indicator cards with pink or lavender
      spots can be returned to a blue color by placing indicators in a sealed container
      with 33 grams (1 unit) of desiccant for four hours. However, we do not recommend
      reversing or using cards that have been exposed to high humidity in excess of 60%
      5. The highest humidity indicator spot should be blue before being put into use.
      6. The humidity indicator will be at its most accurate at a temperature of 23 °C (73 °F).
      7. Avoid contact with indicator spots. Wash any irritated areas with clean water.
      Handling
      1. Store humidity indicators in original sealed container with desiccant when possible
      before using, verify that indicator spots have not changed color
      2. Replace desiccant bag after three openings of container.
      3. Store in dry, cool area.
      4. Keep indicators out of direct sunlight.
      5. Keep humidity indicators away from water or steam.
      6. Ammonia gases will damage humidity indicators.
