HI38033 Total Hardness Test Kit

The HI38033 is a chemical test kit that measures total hardness as CaCO3 by titration with EDTA. The HI38033 is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.
Pre-made reagents for ease of use
All reagents marked with expiration date and lot number for traceability
Manual titration performed with color indicator

Details

The HI38033 is a titration-based chemical test kit that determines the total hardness concentration within the 0 to 30 grains per gallon (gpg) range. The HI38033 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 100 tests.
Features at-a-glance

Complete setup

All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent dropper bottles.
High resolution
Readings from 0 to 30 gpg are determined to 1 gpg resolution.
Replacement reagents available
There is no need to buy a new kit when reagents are exhausted. The HI38033-100 can be ordered to replace the reagents supplied with the kit.

Significance 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. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.
