Hanna HI700 Low Range Ammonia Colorimeter Checker® HC

Hanna HI700 Ammonia Low Range Checker® HC – Handheld Colorimeter for Freshwater

The Hanna HI700 Ammonia Low Range Checker® HC is a compact, handheld digital colorimeter designed for accurate and simple ammonia testing in freshwater environments. Replacing the guesswork and visual limitations of traditional chemical test kits, this device delivers direct digital readings with ease and reliability. With its single-parameter focus, one-button operation, and portable design, the HI700 is ideal for aquarists, educators, environmental monitors, and water quality professionals.

The HI700 uses the Nessler method, adapted from ASTM D1426-92, to detect ammonia concentrations, which appear as a yellow tint during the reaction process. This is especially important in freshwater systems, where ammonia levels serve as critical indicators of organic pollution and toxicity that may threaten aquatic life.
