Hanna Marine Salinity Tester

[Wheelman76]

I just looked up the specs for the Hanna meter , and it looks like the accuracy range is +/- 1 ppt , which I’m not too crazy about. Is this anymore accurate than a good quality refractometer ? I guess it’s still more convenient to use at least.

Its convenience I want. It is as accurate as a good quality refractometer. I have 9 different tanks, quarantine tanks, copepod cultures, water for changes that I have to regularly test this device will make this job a breeze.

If you only have one tank on an Apex controller you likely would not need this tool.

Here is my review:

The good:
Quickly tested 9 tanks.
It automatically adjusts the salinity for the temperature of the tanks
Fairly easy to setup and calibrate
Calibration is good for a month.

The bad:
It uses a cr 2032 battery. Not something you normally would have at home. Expensive battery.
It is only precise to +or-1ppt. Would be nice if it was a little more accurate.
It only uses the hanna calibration solution packs.

All in all I would say for my use it is perfect. Will let you know how it goes in a couple months.

The unit comes with 4 calibration packs so you do not have to rush out and buy the calibration solution.

CR2032's are pretty cheap, can get a two pack of actual branded Energizers at Princess Auto for like 4 bucks.
