PHENOL single-use reagent tablets <\/strong>are designed to accurately measure the pH level<\/strong> in water by photometer. They are an essential consumable for controlling disinfection and correctly adjusting the dosing of treatment products in swimming pools and other aquatic facilities.<\/p>\n

Its formulation is oriented towards a more sustainable chemistry, without boric acid<\/strong>, and offers stable and repeatable readings, even in frequent control routines.<\/p>\n

It is compatible with the entire range of Lovibond Photometers, in particular the Scuba II, Scuba 3S, MD 100, MD 110, MD200, etc.<\/p>\n

What is the Phenol RED reagent used for?<\/h2>\n
    \n
  • Phenol Red:<\/strong> fast and reliable determination for pH level control.<\/li>\n
  • Other compatible parameters:<\/strong> bromine, ozone and monochloramine\/dichloramine (depending on method\/equipment).<\/li>\n<\/ul>\n

    How to use<\/h2>\n
      \n
    1. Place a small amount of sample in the cuvette.<\/li>\n
    2. Add 1 Phenol RED tablet<\/strong> and crush it in the vat.<\/li>\n
    3. Complete with the sample up to the working volume and mix by stirring.<\/li>\n
    4. Take the reading on the Photometer immediately<\/strong> after complete dissolution.<\/li>\n<\/ol>\n

      Main advantages<\/h2>\n
        \n
      • High accuracy<\/strong> in test results.<\/li>\n
