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:
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.
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%.
