AQUADUR TH 400 for total water hardness 91202

Macherey-Nagel

AQUADUR test strips are for the quick and easy determination of water hardness. The convenient Dip & Read procedure and the clear color changes from green to red ensure reliable results within seconds. With AQUADUR TH 400, the total hardness in ppm CaCO3 in water can be measured extremely easily by just scanning one test field.
Total hardness - 0 • 25 • 50 • 120 • 250 • 425 ppm CaCO₃

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