Hanna HI3812-100 Hardness total EDTA titration method

Hanna HI3812-100 Total Hardness Test Kit – EDTA Titration Method

The Hanna HI3812-100 Hardness total EDTA titration method is a reliable and accurate chemical test kit designed for measuring total water hardness using the EDTA titration method. This kit is ideal for both professionals and technicians in laboratories, water treatment facilities, and environmental testing applications who require a simple yet effective way to monitor water hardness.

Features

• EDTA Titration-Based Method
  Utilizes ethylenediaminetetraacetic acid (EDTA) as the titrant for precise measurement of total hardness in water samples.

• Visual Color Change Indication
  Includes a clear color change endpoint that makes detection straightforward. The color transition indicates the completion of the titration.

• User-Friendly Drop Count System
  Reagent is added drop by drop using a manual burette or dropper. The number of drops required to change the solution’s color directly correlates with the hardness level.

• Complete Testing Kit
  Comes with titrant solution, indicator, and necessary reagents. The process is supported by a detailed manual for accurate interpretation of results.
