Location of the desiccant capsules
All instruments ship with fresh reusable desiccant capsules.
They use a cobalt-free colour changing indicator
dye.
Orange indicates fresh desiccant, while green indicates i
t is saturated (about 17% water by weight).
Once
exhausted, the capsules can be replaced with new ones (available from RBR), or refreshed.
Refreshing the desiccant
To refresh the desiccant, saturated silica beads must be removed from their capsule and heated to 120°C for about two
hours. Once cool, refreshed beads can be returned to the capsule and reused.

4.4 Replacing desiccant capsules
Refer to
Opening and closing the instrument
for details on accessing the batteries.
Replace desiccant capsules before each deployment.
Fresh desiccant will keep the instrument compartment dry and prevent malfunction. Water damage may occur if
condensation forms inside the instrument.
As a preventative measure, RBR recommends servicing the instrument in a cool, dry place (when possible).
.
Replacing desiccant capsules
Always remove the beads from their capsule before refreshing! The plastic capsule will deform if heated
to 120°C.
