Aquarium & Marine pocket checkers
Hanna marine and aquaculture checkers offer a cost-effective digital alternative to chemical test kits. Taking the different requirements of all types of aquarium into consideration, the range includes dedicated models designed for use in either fresh or saltwater aquariums. Checkers for marine use can be clearly identified by the ‘fish’ icon.
