Hanna Calcium Hardness Reagents (300 tests) - HI93720-03

Hanna HI93720-03 Calcium Hardness Reagents are high-quality, pre-dosed chemical reagents designed for accurate and consistent colorimetric determination of calcium hardness in water samples. Suitable for use with compatible Hanna benchtop and portable photometers, this reagent set offers enough material for up to 300 tests, making it ideal for laboratories and facilities requiring frequent and reliable water analysis.

These reagents operate using an adaptation of the calmagite method, where calcium ions react to produce a distinct red coloration. This color intensity is measured photometrically, enabling precise and repeatable quantification of calcium hardness across a wide range of sample types. The pre-dosed format simplifies the testing process, reduces handling errors, and ensures consistent results across multiple analyses.

Manufactured in a state-of-the-art facility under strict quality control standards, each bottle is clearly labeled with a lot number and expiration date, ensuring full traceability and supporting laboratory quality assurance protocols. The inclusion of a certificate of quality further enhances confidence in reagent performance and consistency.

Packaged in convenient dropper bottles, the reagents allow safe, controlled, and precise dispensing, minimizing contamination risks and improving workflow efficiency. The high test capacity of 300 measurements makes this kit a cost-effective choice for routine and large-scale testing operations.

Widely used in water treatment plants, environmental monitoring, aquaculture, industrial quality control, and research laboratories, these reagents are essential for maintaining accurate calcium hardness analysis in drinking water and process systems.
