The BRITA Temporary Hardness Testing Kit provides an accurate reading of temporary water hardness (TDS), perfect for setting up the correct bypass on BRITA Purity filtration system s. Use a BRITA drop test kit. Check that the test kit is still in date – see side of box (an out of date kit may give an incorrect reading). The result will determine the bypass setting required on the filter head at installation. Steps: Place 5ml of mains water into the test tube. Add a single drop of the testing solution and gently shake the test tube to ensure the liquids are mixed. Continue to add single drops as above until the water in the tube changes to a bright yellow – this is how hard the water is. Example : One drop = 1 dH Carbonate Hardness, 10 drops = 10 dH Carbonate Hardness BRITA Guide for Correctly Testing Water Show more
