  • Astralpool Free Chlorine (Bromine) and pH Tester

    Tester for measuring free chlorine (bromine) and pH in pool water.

    Chlorine / Bromine Content Test

    1. Fill the left test tube of the tester with the water sample taken from the pool or whirlpool
      up to the 10 ml mark.
    2. Add 5 drops of SOLUTION No. 1 (OTO) or 1 DPD tablet to the test tube. Do not touch the tablet with your fingers, as this would distort the test. Close the test tube with the cap and shake to obtain a homogeneous solution.
    3. Compare the color of the solution with the color chart on the tester. The matching shade determines the amount of total chlorine (free + combined) in mg/liter when using OTO solution, free chlorine when using DPD 1 tablet, or total bromine when using OTO or DPD 1.

    The ideal free chlorine level in a pool is 1 – 1.5 mg/liter (according to Decree No. 135/2004 Coll., 0.3 - 0.6 mg/liter and the maximum permissible combined chlorine level is 0.3 mg/liter). The ideal total bromine level in a pool is 3 - 5 mg/liter.

    pH Test

    1. Fill the right test tube of the tester with the water sample taken from the pool or whirlpool up to the 10 ml mark.
    2. Add 5 drops of SOLUTION No. 2 (RED PHENOL) or 1 PHENOL RED RAPID tablet to the test tube. Do not touch the tablet with your fingers, as this would distort the test. Close the test tube with the cap and shake to obtain a homogeneous solution.
    3. Compare the color of the solution with the color chart on the tester. The matching shade determines the pH value.

    The pH value of water expresses the degree of acidity or alkalinity of a chemical substance. The ideal value for pools is 7.2 - 7.6. A pH higher than 7.6 leads to the formation of various mineral cloudiness, limescale, and other deposits. A pH lower than 7.2 causes corrosion of metal surfaces. The pH value affects the solubility and effectiveness of the disinfectants used.
