The HI3811 is a chemical test kit that measures alkalinity by titration with hydrochloric acid. The HI3811 is supplied complete with all of the reagents and equipment necessary to perform approximately 110 tests.
The HI3811 is a titration-based chemical test kit that determines the alkalinity concentration in samples within a 0 to 100 mg/L (ppm) CaCO3 or 0 to 300 mg/L CaCO3 range. The HI3811 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 110 tests.
All required materials are included with the test kit, such as the sample beakers, plastic syringe, phenolphthalein indicator, and bromophenol blue indicator.
Readings from 0 to 100 mg/L are determined to 1 mg/L resolution Readings from 0 to 300 mg/L are determined to 3 mg/L resolutio.
Replacement reagents available
There is no need to buy a new kit when reagents are exhausted. The HI3811-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (10mL) dropper bottle of phenolphthalein indicator, 1 (10mL) dropper bottle of bromophenol blue indicator, and 1 (120mL) bottle of HI3811-0 reagent.
0 to 100 mg/L (ppm) CaCO₃; 0 to 300 mg/L (ppm) CaCO₃
1 mg/L (0 to 100 mg/L range) 3 mg/L (0 to 300 mg/L range)
acid titration using phenolphthalein and bromophenol blue
