Hanna HI38033-100 Hardness total EDTA method

Hanna HI38033-100 Total Hardness Reagents – EDTA Method (100 Tests)

The Hanna HI38033-100 Hardness total EDTA method is a reagent refill kit designed for measuring total hardness in water samples using the EDTA titration method. This method is widely used for detecting the presence of calcium and magnesium ions, which contribute to water hardness. Although not as precise as digital instruments, this chemical test provides an affordable and accessible solution for many practical water testing needs. With enough reagents for approximately 100 tests, the kit is ideal for fieldwork, education, and general water quality monitoring.

Key Features

• Reliable EDTA Titration Method: This classic technique measures total hardness through a color change reaction that is simple to observe and interpret.

• Drop-by-Drop Accuracy: Reagents are added gradually until a clear endpoint is reached, allowing users to calculate hardness levels based on the number of drops used.

• Cost-Effective Water Testing: While it may not match the precision of electronic meters, this method provides a highly economical and practical alternative.

• Simple and Visual Process: As the reaction progresses, the solution changes color. Once the color disappears, the titration is complete, providing a clear visual cue.

• Ideal for Educational Use: Because of its straightforward methodology, it is an excellent tool for teaching fundamental principles of titration and water chemistry.

• Batch Traceability: Each reagent packet includes a lot number and expiration date to ensure quality control and compliance.

Specifications

• Product Name: Total Hardness Reagents – EDTA Method
