HI3840 Total Hardness Test Kit Low Range The HI3840 is a titration-based chemical test kit that determines the total hardness concentration within the 0 to 150 mg/L range. The HI3840 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. • Complete setup · All required materials are included with the test kit, such as the sample beaker and reagent dropper bottle. • High resolution · Readings from 0 to 150 mg/L are determined to 5 mg/L resolution. Signicance of Use Water hardness has traditionally been dened 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. HI3841 Total Hardness Test Kit Medium Range The HI3841 is a titration-based chemical test kit that determines the total hardness concentration within the 40 to 500 mg/L range. The HI3841 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. • Complete setup · All required materials are included with the test kit, such as the sample beaker and reagent dropper bottle. • High resolution · Readings from 40 to 500 mg/L are determined to 20 mg/L resolution. Signicance of Use Water hardness has traditionally been dened 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.

HI3842 Total Hardness Test Kit High Range The HI3842 is a titration-based chemical test kit that determines the total hardness concentration within the 400 to 3000 mg/L 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. • 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. Signicance of Use 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.
