I use a ton of hanna stuff for a fairly large saltwater aquarium hobby. Their stuff is top notch, but you must calibrate pens often, and or use their reactants, store vials in ro water when not in use, etc.
Regardless of the price and accuracy of the item, it's worthless if you don't use untainted check fluids pretty much every time to calibrate.
So, read up first.
