The HI3842 is a titration-based chemical test kit that determines the total hardness concentration within the 400 to 3000 mg/L (ppm) range. The HI3842 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 50 tests.
Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. Thus, water hardness is actually a quantitative measure of these ions in the water. It is also now known that certain other ion species, such as iron, zinc, and manganese contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.
- Complete setup: All required materials are included with the test kit, such as the sample beaker and reagent dropper bottle.
- High resolution: Readings from 400 to 3000 mg/L are determined to 100 mg/L resolution.
- Replacement reagents available: There is no need to buy a new kit when reagents are exhausted. The HI3842-050 can be ordered to replace the reagents supplied with the kit.
The HI3842 test kit comes with 30 mL hardness HR reagent and 50 mL calibrated vessel.
