Quick Facts – Water Hardness Tester Titrant Double Pack

• Type: Titration test for water hardness
• Quantity: 2 reagent bottles
• Volume: 2 × 9 ml
• Measurement scale: French hardness scale (°fH)
• Shelf life: Over 12 months
• Included: 2 reagent bottles, graduated test tube, instructions

This double pack of Titrant water hardness testers provides an easy and accurate way to measure the hardness of your water. Each bottle contains 9 ml of reagent, sufficient for numerous measurements. The package also includes a graduated test tube and clear instructions. The new formula lasts over 12 months and requires no refrigeration.

The test uses the French hardness scale (°fH), which provides more accurate results than the German scale. The method is simple: add the reagent drop by drop to the water until the colour changes from red to green. The number of drops indicates the water hardness directly in °fH. The result shows whether your water needs softening.

Why choose the Titrant water hardness tester?

The Titrant method is the most reliable for home use. With two bottles in the package, you can perform regular tests over a long period. The long shelf life and easy storage without refrigeration makes the test practical for all households. Perfect for checking water softeners, optimising detergent dosing or investigating water quality in a new home.

How to use the test

1. Pour 5 ml of the water to be tested into the test tube (first marking from the top). 2. Add the reagent drop by drop and mix gently after each drop. 3. Count the drops until the water changes colour from red to green. 4. The number of drops equals the water hardness in °fH.

Water hardness scale

Tip: When hardness exceeds 15 °fH, water softening is recommended to protect household appliances and reduce limescale buildup.

Frequently Asked Questions about Titrant Water Hardness Tester

How many tests does the package provide?

With 2 × 9 ml of reagent, the double pack provides enough for a large number of measurements. The exact number depends on water hardness, as harder water requires more drops per test. On average, you can perform dozens of measurements.

What is the difference between French and German hardness scales?

The French scale (°fH) is more detailed than the German scale (°dH). 1 °dH equals approximately 1.78 °fH. The French scale therefore provides more precise readings, which is beneficial when fine-tuning water softener settings.

Does the test need to be stored in a refrigerator?

No, the new formula requires no refrigeration. The reagent lasts over 12 months at room temperature, making it convenient to keep at home.
