  1. What factors affect the amount of desiccant needed in an enclosure?

    There is not an easy way to calculate how much desiccant is needed in an enclosure or how quickly the desiccant will need to be replaced. The following conditions affect the replacement interval:

    • How much humidity the enclosure is exposed to
    • The size of the enclosure
    • How often the enclosure door is opened and how long the door remains open
    • How airtight the enclosure is

    It may be advantageous to use more than one desiccant packet at a time inside an enclosure. Campbell Scientific recommends keeping an extra supply of desiccant on hand for as-needed replacement in the enclosure.

  2. When should the desiccant inside an enclosure be replaced?

    The desiccant should be replaced when the top colored dot on the humidity indicator card (pn 28878) turns pink; the humidity indicator card is included in the enclosure supply kit that is shipped with each enclosure. If the CS210, Enclosure Humidity Sensor, is used, replace the desiccant when the measured humidity exceeds 35%.
