7 in 1 Tester for Pool Water and Spa, 100 Pieces Swimming Pool Strips, Pool and Spa Tester, Bromine Total Alkalinity and pH, Total Hardness

Each box contains 100 water quality test strips, packaged in an airtight moisture-proof container. Close the bottle cap tightly after each use to ensure long-term preservation. Strips quickly absorb water samples and provide accurate reactions. They resist softening and damage during testing and feature clearly separated color areas to avoid interference between indicators. No special knowledge is required to achieve results. Simply immerse the strip in the water sample for 2 seconds, remove it and let it sit horizontally for 30 seconds. Compare the result with the supplied colour chart to get an accurate measurement in 30 seconds. Suitable for daily analysis of tap water and home drinking water; also ideal for monitoring the water quality of pools and spas, providing full coverage. Note: Do not touch the test strip with wet fingers. Read the results in natural light for optimal accuracy. Store in a cool and dry place.
