Hi I just purchased the Hanna salinity tester and it won’t calibrate. When I put it in the solution it just goes to err. Any ideas on how to fix this issue?
Return it. I had this issue with a brand new one a couple months ago, took it back to my LFS and they opened two more brand new units that were defective as well.
I meant to follow up with them but I assume there was a bad batch of units.
Same here. Just err on calibration. I returned it to the store for a new one but that one couldn't hold it's calibration for a hour. So returned it once more. This one holds up but once this breaks I'm done with them.
The other checkers I have no problem with but the salinity one I'm not a fan of even if testing is simple with it.
