Old Hanna meter still good?

[PSU4ME]

I have a Hanna phosphate meter that’s at least 5 years old, likely 6-7. Still it ins case and all. I know I’ll need new reagent but do you think the device itself is still good or do these things have a shelf life?

Should be OK with new batteries as long as there is no corrosion.
You can always check it with a test kit..

Yeah that was my plan, check it against a working kit. I’ll give it a whirl and save the $50
