Effortless water quality monitoring for home use. This kit delivers 23 testing items across 158 tests, covering hardness, residual chlorine, pH, total alkalinity, cyanuric acid, copper, iron, lead, manganese, aluminum, zinc, bromine, nitrate, sodium chloride, and more. The kit includes strips, Pasteur pipettes, and test tubes for a complete, single-kit testing setup. To operate, immerse a test strip for 2 seconds, wait 30 seconds, and compare against the color chart, which is the same size as the strip for easy reading. It works with drinking water, well water, tap water, pipeline water, rainwater, spring water, stream water, pool water, and water in spas and hot tubs. Compact and portable, the kit stores neatly and is designed to prevent cross-contamination between water sources.
