Hanna Instrument’s line of Checkers (handheld colorimeters) has a longstanding following with aquarists. At least two new Checkers have been announced, and they will expand the range of parameters that aquarists can quickly test. The first is the new pH Checker, a high-range version for use with saltwater. Hanna expects to start shipping the HI780 Marine pH Checker HC in July 2020.

Hanna Checkers take the guesswork out of color comparisions.

Hanna’s Marine pH Checker, at a Glance

Get accurate water testing results with the HI780 Marine pH Colorimeter. With a digital readout, there is no more struggling to determine colors visually. This pH tester’s compact design fits in your pocket or stores easily in your shop.

The HI780 Checker®HC (Handheld Colorimeter) is a simple, accurate, and cost-effective way to measure pH in saltwater.

pH is a measure of the hydrogen ion concentration in your water; the higher the concentration, the more acidic the water is. A neutral pH is 7; most fish can live in a general range between 6 and 8. Keeping your aquarium pH stable and in optimal ranges reduces stress on your fish and aquatic animals, helping them resist disease and tolerate other stressors. Maintaining an ideal pH can also dramatically improve growth, behavior, and overall appearance.

Designed as a more accurate alternative to chemical test kits, the HI780 marine pH meter provides quick, accurate results in a few easy steps.

Features at a glance:

  • For use with saltwater samples
  • Easier to use and more accurate than chemical test kits
  • One-button operation makes getting your pH results simple

  • Small size, big convenience
  • Ideal for aquariums and marine biology applications.
