Hanna HI775-26 Reagents for Alkalinity Checker

Hanna HI775-26 Reagents for Freshwater Alkalinity Checker HC

The Hanna HI775-26 Reagents for Alkalinity Checker is specifically designed enabling users to perform fast, accurate, and consistent alkalinity testing. These high-quality, pre-measured reagents follow a colorimetric method, where a color change occurs in the sample—from yellow to green to blue—based on the alkalinity level.

Each packet contains the precise amount of reagent needed for one test, ensuring accuracy and ease of use for aquarium hobbyists, water treatment professionals, and environmental field testers.

Key Features:

• Pre-Measured for Convenience: Each packet contains the exact amount of reagent needed for one test—no measuring or handling of chemicals required.

• Colorimetric Accuracy: Reagent reacts with the sample to produce a color gradient that is read by the HI775 Checker and displayed in ppm.

• High-Quality Chemicals: Manufactured under stringent conditions to ensure consistency, accuracy, and shelf stability.

• Designed for Freshwater Testing: Optimized for analyzing alkalinity in freshwater environments such as aquariums, rivers, lakes, and drinking water systems.

How It Works:

1. Fill the cuvette with a freshwater sample.

2. Add the contents of one HI775-26 reagent packet.

3. Mix gently.

4. Insert the cuvette into the HI775 Checker HC.

5. The alkalinity reading is displayed in ppm (as CaCO₃).
