Hanna Marine Salinity Tester

[Frogger]

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.
