• CAL Check to verify meter performance

• The HI97101 offers multiple methods in one meter. The determination of bromine, chlorine, and iodine uses the DPD method; the determination of iron uses a modification of the TPTZ method; the determination of pH uses the Phenol Red method; the determination of cyanuric acid uses a modification of the turbidimetric method. Depending on the parameter being measured, reagents are available in powder and liquid form.

• Chlorine is the most commonly used water disinfectant for homeowners, hotels, and commercial establishments. In swimming pools, spas, and similar applications, cyanuric acid helps stabilize chlorine and prevent its decomposition, especially in sunlight. Frequent testing of cyanuric acid and pH helps reduce chlorine consumption. The disinfecting properties of bromine and iodine have led to their use as alternatives to chlorine. One of the most common applications of iodine is in production water for the poultry industry, while bromine is used for disinfection of cooling towers, pools, and spas.

• When a suitable reagent is added to the sample, a color change is displayed; the higher the concentration, the deeper the color. The relevant color change is then analyzed colorimetrically according to the Beer-Lambert law. This principle states that light is absorbed by the complementary color, and the emitted radiation depends on the concentration. For the determination of all six parameters, a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the color change of the reacted sample increases, the absorbance of light at a specific wavelength also increases, while transmittance decreases.
