About This Product

■Description

The HI3811 is a titration-based water quality test kit that measures the alkalinity concentration of a sample within the range of 0-100mg/L (ppm) CaCO3 or 0-300mg/LCaCO3. HI3811 comes with all necessary reagents. The test kit contains enough reagents to perform approximately 110 tests. Feature overview

■Completion of setup

All necessary materials are included in the test kit, including a sample beaker, plastic syringe, phenolphthalein indicator, and bromophenol blue indicator.

■High resolution

Measurements from 0 to 100 mg/L are determined with a resolution of 1 mg/L. Measurements from 0 to 300 mg/L are determined with a resolution of 3 mg/L.

■Replacement reagents available

There is no need to purchase a new kit even if you run out of reagents. For the HI3811-100 reagent set, you can order the reagents used in the kit. This reagent set includes one dropper bottle (10 mL) of phenolphthalein indicator, one dropper bottle (10 mL) of bromophenol blue indicator, and one dropper bottle (120 mL) of HI3811-0 reagent.

■Advantages of using

Alkalinity is the quantitative ability of sample water to neutralize acids and reach a set pH. This measurement is very important in determining the corrosion properties of water, mainly due to hydroxide, carbonate, and bicarbonate ions. Other sources of alkalinity can come from anions that can be hydrolyzed, such as phosphates, silicates, borates, fluorides, and salts of some organic acids. Alkalinity is important in drinking water, wastewater, boiler and cooling systems, and soil treatment. Alkalinity can be measured as phenolphthalein alkalinity and total alkalinity. Phenolphthalein alkalinity is measured by neutralizing the sample to pH 8.3 using a dilute hydrochloric acid solution and a phenolphthalein indicator. This process converts hydroxide ions to water and carbonate ions to bicarbonate ions.

■Accessories

The HI3811 test kit comes with 10mL phenolphthalein indicator, 10mL bromophenol blue indicator, 120mL alkalinity titrant, 10mL calibration vessel, 50mL calibration vessel, and calibration syringe with tip.
