8.4 Sealing and Desiccating the Enclosure
Campbell Scientific enclosures include an Enclosure Supply Kit with the
following items:
(4) Desiccant packs
(1) Humidity indicator card
(6) 4-inch cable ties
(6) 8-inch cable ties
(4) Cable tabs
(1) 4 oz. sealing putty
Items in the Enclosure Supply Kit are used to strain relief the sensor leads, seal
