Calcium Hardness Reagents (300 tests) - HI93720-03
The HI93720-03 are reagents for the colorimetric determination of calcium hardness. There are enough reagents for 300 tests to be used with a compatible benchtop or portable photometer. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each bottle for traceability.
- Pre-dosed reagents for ease of use
- Supplied with certificate of quality
- Marked with expiration date and lot number for traceability
The HI93720-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the calmagite method. The reaction between calcium and the reagents causes a red tint in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible benchtop or portable meter can be used to determine the concentration from the color that is produced. The results will be displayed in mg/L (ppm) as calcium carbonate (CaCO3). These reagents are designed to be used with samples that have an expected range of 0.00 to 2.70 mg/L calcium hardness.
Compatible Photometers Include:
|Method||Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, calmagite method. The reaction between calcium and reagents causes a red tint in the sample.|
