Hanna Alkalinity Tester
- Low stock - 1 item left
- Backordered, shipping soon
The Hanna Alkalinity Checker (HI772) takes the guesswork — and the color-matching squint — out of the single most important reef parameter. Add your sample, add the reagent, press the button, and read your dKH as a digital number. No interpreting shades of pink at the kitchen window.
Why alkalinity first: stable alk is the backbone of coral health — swings show up as tissue loss and stalled growth before anything else does. A digital checker makes daily or every-other-day testing fast enough that you'll actually do it, which is the whole battle.
- Digital dKH result in about a minute — no color matching
- ±0.05 dKH resolution, marine-specific range
- Pocket-sized; pairs with Hanna alkalinity reagents (we stock those too)
