This document describes the HI 38034 Total Hardness 0-20 gpg range test kit. The kit allows for easy and quick monitoring of water hardness to prevent scaling and clogging in water pipes.
The document provides instructions for using the Hanna Instruments HI 38034 Total Hardness Test Kit. This kit measures water hardness by determining calcium and magnesium ion concentrations in a sample via EDTA titration. It includes necessary reagents such as buffer solution, Calmagite indicator, and specific EDTA solutions for gpg or ppm ranges.
The kit measures total hardness from 0 to 20 gpg or 0 to 20 ppm.
You must fill the plastic vessel to the 25 mL mark with your water sample.
The solution changes from red-violet to blue when the endpoint is reached.
