Product description

Product Description Aquadur are test-strips for the determination of water hardness. Clear colour changes from green to red ensure an accurate readout within seconds. Individually sealed AQUADUR test strips can perfectly be combined with promotion activities to inform customers about the necessity of water softeners. Instructions for use are printed on the seal. Due to the clear design with green/red indication, a colour chart is not necessary. The hardness of water depends on its content of calcium and magnesium salts. The total assay of these salts determines the hardness of water, which can be expressed in terms of ppm (mg/l). Water can be classified as 'soft water' or 'hard water' depending on the concentration of the salts: below 50ppm CaCO3 - very soft water. 50-120ppm CaCO3 - soft water. 120-240ppm CaCO3 - medium hard water. 240-360ppm CaCO3 - hard water. Above 360ppm CaCO3 - very hard water. These test strips are semi-quantitative test strips for the quick and easy determination of water hardness. Directions Dip the test strip into the water sample, wait for the color to change, and then read the result within seconds.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
