User Maintenance
Overview
It is important for users to perform scheduled
maintenance on their instruments to sustain the
accuracy and longevity of the probes and cables. The
frequency of this maintenance depends on the
characteristics of the deployment site, including
humidity levels and the degree of fouling.
Users should be aware of the conditions at their
deployment sites and develop appropriate maintenance
schedules to replace desiccant, clean the instruments,
and send in the instruments for factory calibration.
Users should check instruments often during the first
portion of the deployment to determine the frequency of
maintenance. General maintenance should be
performed as often as possible. Factory service should
be performed at least every 12 months.
Preventing Condensation
Desiccant
Desiccant protects electronics from condensation,
which can cause irreparable damage and loss of data.
Indicating desiccant changes from blue to pink as it
becomes saturated with moisture.

It is extremely important to use a properly-sized
desiccant for your deployment, and to change
desiccant often. Desiccant should be changed before
the entire volume has turned pink, and you should use
enough desiccant to effectively keep cables,
instruments and electrical boards dry until your next
scheduled maintenance. Desiccant life span is
dependent on site conditions.
Desiccant Pack Options
Small Desiccant
The Small Desiccant is a disposable cap that ships with
In-Situ Inc. products. The small desiccant is meant to
protect the instrument and cable only during
shipping, and should not be used for
deployments.
Large Desiccant
The Large Desiccant is a replaceable desiccant pack
designed for low-humidity environments or
deployments where maintenance occurs frequently.
The large desiccant is available with a plastic or a
titanium twist-lock connector.
