Water is enriched with countless substances. Ideally, these are substances that are beneficial to health, even vital, in certain quantities. Unfortunately, substances also accumulate in water that are very harmful to health in the long term. If not handled properly, dangerous germs and pathogens can even form in water. This is why the law requires owners of heating and drinking water treatment systems above a certain size to have their water analysed regularly. With our drinking water analysis in Frankfurt, you are always on the safe side!
Drinking water test complete
Drinking water test complete is the most comprehensive water analysis in our range.
This water analysis determines the quality of your water.
We analyse the water for microbiological parameters and advise you on all questions relating to the purity of your drinking water
The water is analysed for the most common impurities and compared with the limit values of the Drinking Water Ordinance.
This allows you to see at a glance whether your water fulfils the measured parameters.
Microbiological parameters:
- E. coli
- coliform germs
- Colony count at 22 °C and 36 °C
