AQUADUR® • Quick and easy determination of water hardness • 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. • The water hardness depends mainly on the amount of calcium and magnesium salts within the water. • The total sum of these salts determines the actual water hardness. • In the USA, water hardness is expressed in ppm (mg/l) CaCO3. • Generally, water is often simply classified as “soft” or “hard” water. • By and large, the following values apply to these terms: • below 50 ppm CaCO3– very soft water • 50 – 120 ppm CaCO3– soft water • 120 – 240 ppm CaCO3 – medium hard water • 240 – 360 ppm CaCO3 – hard water • above 360 ppm CaCO3– very hard water • Water hardness plays an important role in everyday life and a wide variety of industries and applications. • Hard water can even adversely affect taste and appearance of food. • Hard water inhibits the lathering of soap, so more detergent has to be used in hard water in order to achieve the same cleaning results as in soft water. • Additionally, hard water may cause calcification and can thus damage machinery, appliances, pipes or heating units. • In many industries, water hardness is an important parameter in process control and has to be monitored constantly. • Some examples of industries include the textile industry, dyeing factories, large scale laundries, water works and fish-farming and aquaculture • AQUADUR® water hardness test strips are the ideal choice to quickly, easily and reliably determine water hardness. • Presentation: 5000 test strips, withour colour scale • Gradation: <55 · >70 · >125 · >250 · >375 ppm
