Hanna Calcium Hardness Checker® HC Reagents (25 Tests) - HI720-25

HI720-25 Calcium Hardness Checker HC Reagents provide a reliable solution for accurately determining calcium hardness in water samples. Suitable for laboratory, water treatment, pool maintenance, and industrial quality control, these reagents are designed for use with the HI720 Calcium Hardness Checker HC device.

Each unit contains 25 pre-measured reagent packets based on the Calmagite method, following the adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition. The Calmagite method involves a reaction between calcium ions and reagents, which creates a reddish-violet tint in the water sample—this visible indication ensures precise calcium measurement every time.

• Contains 25 pre-measured reagent packets for Calmagite method analysis.
• Designed as replacement reagents for the HI720 Calcium Hardness Checker HC.
• Ensures high-purity testing with enhanced measurement accuracy.
• Each reagent packet is marked with lot number and expiration date for traceability.
• Adaptation of Standard Methods for the Examination of Water and Wastewater, 18th edition, Calmagite method.
• Produces a reddish-violet tint to indicate calcium presence in the sample.
• Convenient and ready-to-use packaging for rapid, reliable hardness measurement.

This pack is ideal for use in environmental monitoring, laboratory water testing, swimming pool maintenance, industrial water treatment facilities, and more. Simply add the reagent to your water sample and measure calcium hardness using the compatible Checker HC device.
