Quick test sticks Aquadur®, for evaluation of water hardness, 100 unit(s)

Quick test to guide semi-quantitative determination of water hardness (total hardness).Measuring range of 0 °d to more than 25 °d. Conversion: 1 °d = 1.8 °f = 1.25 °e = 17.8 mg/l CaCO₃.One box contains 100 test strips W 6 x L 95 mm.

Application:the test strip is briefly dipped into the water to be measured. After approximately one minute, the colouring that has appeared can be compared to a colour scale and the hardness range can be determined.Caution: the test paper must not come into contact with fingers.
