Test Strips Test strips in a variety of parameters. High-quality Hach chemistry on an easy-to-use test strip. Simply dip the strip in sample and compare with colors printed on the bottle to fi nd a reading. Test strips are accurate, portable, and low-cost. Applications include drinking water, wastewater, pool and spa, industrial process water, and more. Parameters available include chlorine, nitrate and nitrite, hardness, alkalinity, chloride, ammonia, and more. Hach o ff ers a high-value 5 in 1 test strip, which measures free chlorine, total chlorine, hardness, alkalinity, and pH - all on one strip.
