The pH value test strips help you determine the pH value. If this is too high with the pH tester, this results in limescale deposits, eye and skin irritation, as well as cloudy fittings.
Measuring water hardness is important with water hardness test strips, because too hard water is bad for dishwasher, washing machine etc. and a strain on skin and hair.
Check the quality of your water regularly with our drinking water test strips. Test up to 21 parameters and protect your health from possible pollutants in the water.
Although our water is strictly controlled by the water tester, heavy metals such as lead, chrome or zinc can also be released from old water pipes and medicine residues are difficult to filter out by waterworks.
