The AQUAPHOR water hardness tester is a simple drop test for measuring hardness in German degrees (°dH). Just add drops of the reagent to the sample and mix until the color changes to green, and the number of drops corresponds to the result in °dH. The kit is suitable for home use, aquaristics, and for setting up devices such as water softeners, coffee machines, washing machines, and dishwashers.

Description
The AQUAPHOR water hardness tester, dH drop test, is a practical and accurate kit for quickly measuring water hardness in German degrees (°dH). It works well at home, in aquaristics, and anywhere water parameters need to be controlled — with devices such as a water softener, coffee machine, washing machine, dishwasher, or a home water filter. It is convenient support for everyday water treatment and for checking whether the water filtration system is performing as expected.
The measurement is carried out using the drop test method: successive drops of reagent are added to the water sample until the color changes to green, and the number of drops corresponds to the result in °dH. The kit is reusable, easy to use, and ready for regular water checks in home installations.
Precise drop test for everyday water hardness monitoring
The AQUAPHOR tester has been designed for convenient and clear water hardness checks. It is a solution for people who want to consciously control water parameters in the household, with household appliances, and in aquaristic applications.
Thanks to measurement in German degrees (°dH), it is easier to choose the right device settings, assess the efficiency of the installation, and respond to changes in water quality. The tester can be useful both with classic solutions and where a water softener, osmosis filter, reverse osmosis system, or other water filtration system is used.
Key features and benefits
- Measurement accuracy – the possibility of measuring with an accuracy of 1°dH or 0.5 °dH.
- Reusable – the kit includes about 300 drops of reagent, which ensures repeated use.
- Ease of use – a simple test procedure consisting of adding drops to the water sample until the color changes.
- Complete kit – the set includes a reagent bottle, a measuring vessel, and an instruction manual.
This practical tool allows you to quickly obtain a result and check the water hardness without complicated equipment. Regular measurement helps better protect devices exposed to limescale buildup and more accurately adjust the operating parameters of treatment systems.
Applications of the AQUAPHOR tester
The dH drop test is useful wherever water hardness matters for user comfort, device durability, and installation performance.
- Commissioning and control of water softeners.
- Adjusting water hardness in coffee machines, washing machines, and dishwashers.
- Checking water hardness in home installations and aquaristics.
In practice, this means convenient control both in everyday home use and in more demanding systems where water parameters affect operation, beverage taste, dish cleanliness, or the condition of equipment.
How to perform a water hardness test
The test procedure is simple and intuitive, so even people who have not previously measured water hardness can use the kit.
- Rinse the measuring vessel with the water being tested.
- Pour the appropriate amount of water into the vessel.
- Add drops of reagent, stirring until the color changes to green.
- The number of drops corresponds to the water hardness in °dH.
To obtain repeatable results, it is worth carrying out the measurement in a clean vessel and counting the drops carefully, one by one. The tester does not require refrigerator storage, which makes everyday use and storage at home easier.
Water hardness scale
The result can be interpreted according to the scale below:
- 0-7 °dH – soft water.
- 8-14 °dH – moderately hard water.
- 15-21 °dH – hard water.
- 21 °dH – very hard water.
This classification makes it easier to assess whether the water requires further parameter adjustment and whether the settings of devices or installations are appropriate to the current conditions.
Kit contents
The package contains all the elements needed to start measuring:
- Measuring reagent (15 ml).
- Measuring vessel with stopper.
- Instruction manual.
- Protective kit packaging.
Operation and ease of use
The tester is designed for repeated use. The amount of reagent allows many tests to be performed, and about 300 drops provide a convenient reserve for regular checks.
Another major advantage of the kit is easy storage — the reagent does not need to be kept in the refrigerator. As a result, the tester can always be kept close at hand, for example in the kitchen, near the home water treatment station, or in the area where household appliances are operated.
Why it is worth measuring water hardness regularly
Monitoring water hardness allows more accurate decisions regarding device operation and water treatment system settings. This is especially important when a water softener is used at home, or a system such as a reverse osmosis filter, reverse osmosis, or another water filter requiring conscious control of inlet or final parameters.
Regular measurement makes it easier to assess device performance, helps monitor changes in water quality, and supports everyday prevention of limescale deposits. The AQUAPHOR tester is a simple way to do this quickly, conveniently, and without specialized equipment.
