Yes, Hanna Instruments makes many measuring devices. The Marine line is a fraction of their total product catalog. For instance if you have a pool, they make checkers for testing chlorine and other elements too. That is why it is important to verify if the checker you see is made for saltwater. Many are not.

Sorry, couldn't resist. Interesting trivia note: they tried various liquids to try and get the look/consistency of maple syrup but failed and ended up using mostly (actual) maple syrup.
