The Replacement DO Sensor Cap replaces the original DO sensor cap that’s included with the HOBO DO Data Logger. The DO sensor caps have a 6-month deployment life. (The caps expire 7 months after initialization to allow some time before and after the deployment.) The caps have a 2-year shelf-life from the date they were manufactured. (Shelf-life shown on the canisters the caps come in.)
This replacement operates in outdoor and underwater environments.
