• HI93735-00 are high-quality pre-dosed reagents that allow users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of EPA recommended method 130.1, in which the reaction between calcium, magnesium, and the reagents causes the sample to take on a red-violet tint. By simply adding liquid reagent A, two drops of reagent B, and reagent packet C to the sample, the reaction between calcium and magnesium and the reagents causes a color change that depends on the concentration. The color intensity is determined by a compatible HI96735 photometer, and the concentration is displayed. Results are displayed in mg/L (ppm) of CaCO3. These reagents are designed for samples with an expected range of 0 to 250 mg/L (ppm) CaCO3 total hardness.
