Hanna Checker Colorimeters

Hanna Checkers are some of our favorite test kits for testing our reef tanks. These small and innovative little egg-shaped devices make our aquarium-keeping lives so much easier with simple testing procedures and most importantly – an all-digital readout! Perfect for every aquarist, but especially those that struggle determining the color scale on standard test kits.
