Leider haben freundliche Zeitgenossen sowohl die Anleitung (die Zeiten sind wichtig!) als auch die Farbtabelle jeweils mit einen schönen Aufkleber überdeckt. Ich hatte große Freude daran, selbige zu entfernen. Im Auslieferungszustand also leider unbrauchbar, einen Extrastern gibt es weil die Messstreifen offenbar tun was sie sollen.

I bought these strips to check for myself definitively that a water softener I recently had installed is actually working.As the attached photo shows, there is a very clear difference between water from the softener on the left (strip remains the colour it started off with - green, indicating zero hardness) and previous hard water on the right (strip goes brown, indicating hardness is present). To be doubly sure I didn't happen to pick a 'dud' strip for the soft water, I dried it off with a tissue, then put that same strip in the hard water, and it too then went brown.So for the basic confirmation of softness I was seeking, it was plenty good enough. The actual level of hardness isn't fully reflected though, the colour suggested about 120ppm, but I know the figures from my water company are about 285ppm. 100 strips for £5.99 wasn't too bad.

idéal, pour être sur que l'eau du robinet et bonne a boire.
