Improve the accuracy of your results for your saltwater aquarium with Hanna's simple handheld colorimeter. The HI755 alkalinity colorimeter closes the distance between alkalinity test kits and advanced instrumentation.

  • The HI755 handheld colorimeter is portable and fits right in your pocket.
  • Get your alkalinity results easily with simple one-button operation.
  • Don’t worry about matching the right color, the HI755 colorimeter does it for you.
