AQUADUR Sensitive, for water hardness 91243

AQUAUDR Sensitive water hardness test strips include all the same benefits as the classic AQUADUR test strips, but feature a special, very low measuring range.

Total Hardness - 0 • 5.4 • 10.8 • 18.8 ppm CaCO₃

AQUADUR® test strips are for the quick and easy determination of water hardness 91201

AQUADUR^® test strips are for the quick and easy determination of water hardness. The convenient dip & read procedure and the clear colour changes from green to red ensure reliable results within seconds.
