Replacement Hanna DO Probes
If your hanna dissolved meter has kicked the bucket it is probably just the DO probe that will need to be replaced.
Here at water-testers.com we offer a full line of Hanna replacement probes. To ensure a long lifetime in aquarium water we suggest you store your Dissolved oxygen on storage solution.
After each use you should use cleaning solution as well and this will give you a longer lifetime.
Remember these solutions can be Hanna brand or Milwaukee instruments.
