Hanna Instruments HI772 Checker Saltwater Alkalinity Colorimeter (dKH)

Product details

Hanna Instruments HI772 Checker Saltwater Alkalinity Colorimeter (dKH) is a handheld test tool made for measuring saltwater alkalinity and displaying the result directly in dKH. If you’ve used standard aquarium alkalinity test kits that require matching colors to a chart, this colorimeter streamlines the process by removing the need to visually interpret subtle color changes. It’s a practical upgrade for keeping your reef or saltwater system’s alkalinity on track, helping you build a consistent testing routine without the chart-matching step.

Features:

• Provides a direct saltwater alkalinity reading in dKH units rather than relying on color-chart matching
• Handheld, portable design intended for easy use during routine water testing
• Simple one-button operation to make results quicker and less subjective
• Helps bridge the gap between basic alkalinity test kits and more instrument-style measurement
• Works as an alkalinity-focused measurement tool for saltwater aquariums
