Hanna HI720-25 Calcium Hardness Checker reagents

Hanna HI720-25 Calcium Hardness Checker HC Reagents – 25 Tests

The Hanna HI720-25 is a set of 25 high-quality, pre-measured reagent sachets designed for use with the HI720 Calcium Hardness Checker HC. These reagents follow a colorimetric EDTA method, where calcium ions in the sample react with the reagent to produce a measurable color change. As a result, the Checker HC determines calcium hardness levels and displays the result in ppm (mg/L) as CaCO₃.

Thanks to the pre-measured format, users can perform tests quickly and accurately, without requiring any additional preparation. Consequently, the HI720-25 is ideal for professionals and hobbyists alike, offering reliable performance across a wide range of water quality applications.

Features

• Pre-Measured & Easy to Use: Each sachet contains the exact amount of reagent needed for one test. Therefore, there is no need for manual measurement or dilution.

• Accurate EDTA-Based Method: The reagents produce a color change proportional to calcium concentration, which ensures precise and consistent readings.

• Fast Results: With just a few steps, you can obtain accurate results in under a minute when used with the HI720 Checker®.

• High-Purity Chemicals: These reagents are produced under controlled conditions using reagent-grade materials. As a result, they maintain excellent consistency from batch to batch.

• Traceable & Reliable: Each packet is labeled with a lot number and expiration date to support full traceability and quality control.
