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 storage caps provided, making sure that each container is filled with the original storage solution or clean water. If the storage containers have been misplaced, order replacements here or keep extra on hand.
