Very little maintenance is required for T-Node FR temperature strings because they are designed for long-term deployments in submersible applications.
Any bio-fouling that accumulates on T-Node FR temperature strings during deployments should be cleaned using a soft cloth or soft-bristled brush along with soap and water. Never allow moisture to enter any of the UW connectors during cleaning.
T-Node FR temperature sensors should be stored in a cool, dry place.
Although T-Nodes are capable of holding the initial factory calibration indefinitely, temperature strings may be sent in for a factory recalibration every two years to ensure maximum sensor performance.
