    The HI772 Checker®HC (Handheld Colorimeter) provides a simple, accurate, and cost-effective way to measure alkalinity in marine aquariums. Get accurate results for your saltwater aquarium with our simple handheld colorimeter. Our alkalinity colorimeter bridges the gap between alkalinity test kits and advanced instrumentation.
