Broken Hanna Salinity Checker

Nick Rose · Jan 8, 2021

Some how water got into my Hanna Salinity checker. It turns on but doesn’t display a reading. I think it’s over a year old. I did put in a new battery to see if that was it but it wasn’t.

I had the same problem with an underwater camera. It never worked again.

Im a new reefer so I admit Im not an expert at all but I went from my optical refractometer to the Hanna digital refractometer (https://www.hannainst.com/hi96822-digital-refractometer-for-seawater-analysis.html) for $180. I consider the following to be essential to the reef aquarium (In order of importance): Temperature, salinity, alk, nitrate, phos and I measure them regularly.

I find the digital refractometer very easy to keep clean and very easy to use. It is very fast compared to a optical refractometer. That being said, I do still have my BRS Optical refractometer that I keep calibrated because I don't like to get rid of things. Whenever I check the optical refractometer it is SPOT ON compared to my digital meter.

I was able to fix it. I had some damp rid so decided to put some in a container and put the Hanna checker in. This morning I put the battery in and it now shows the numbers clearly.

So if anyone has water that gets into there Hanna or any other devices try using damp rid.

Interesting that water got in somehow. It's supposed to be waterproof.

I know I thought it was strange too. But I noticed water in the corner of the display area.

Wonder if it got in through the LCD?

I know I've had mine completely submerged plenty of times and haven't had an issue.....yet.
