  • Astralpool Active Oxygen and pH Tester

    Tester for measuring active oxygen and pH levels. The tested water changes color and is compared with the color shade on the tester, which is assigned a numerical pH value or free chlorine value. The reagent tablets are intended exclusively for chemical analysis and must not be used for any other purpose.

    The tester comes with a pack of 20 tablets for measuring pH and 20 tablets for measuring active oxygen.

    • Ideal oxygen level: 5.0 - 8.0 ppm
    • pH range: 6.8 - 8.2
    • pH values lower than 6.8 always produce a yellow color
    • pH values higher than 8.2 always produce a red color
    • Water samples with low carbonate hardness
      (acid-binding capacity 4.3 < 0.7 mmol/l) may
      distort pH values.

    The pH value of water expresses the degree of acidity or alkalinity of a chemical substance. The ideal value for swimming pools is 6.8 - 8.2. A pH higher than 8.2 leads to the formation of various mineral cloudiness and the buildup of limescale and other deposits. A pH lower than 6.8 causes corrosion of metal surfaces. The pH value affects the solubility and effectiveness of the disinfectants used.
