SENSOR STORAGE
Exposure to atmospheric conditions will cause the sensor tips to dry out. Always
remove and properly store sensors in the soaking caps provided if sensors are to be
removed or stored for one hour or longer. Although CAT Professional Series
sensors are freeze-resistant, they must be protected from freezing temperatures
when not in use.
Store sensors in the soaking caps provided, making sure that each container is filled
with the original storage solution or clean water. If the storage containers have been
misplaced, store sensors individually in small glass or plastic containers with clean
water covering sensor tips.
CONTROLLER STORAGE
The controller unit is subject to damage by electro-static discharge (ESD) when the
sensor cables are disconnected. Always reinstall the BNC protective covers prior to
storing or transporting the CAT 4000controller unit.
WINTERIZATION
The sensors should be prepared for storage as outlined above and protected from
freezing temperatures. Although the CAT 4000 controller is designed to withstand a
broad temperature range, winter storage in a secure location may be desirable.
The flow cell and poly tubing must be drained prior to exposure to freezing
temperatures. Either purge all water using compressed air or thoroughly drain
through the valve ports and tubing connections.
