HOCL or Sodium Hypochlorite Liquid Can Be Produced within minutes This machine can generate both hypochlorite solution and sodium hypochlorite solution (bleach), depending on the pH value of the sodium chloride solution. When the pH is 5-6 you will get hypochlorous acid, when the pH is higher you will get sodium hypochlorite (bleach). Machine has 3 different settings: Low Strength 5 mins, Mid Strength 10 mins or High Strength 30 mins If you want hypochlorous acid instead of sodium hypochlorite, you should use a ph test paper to verify that the ph is between 5 and 6 before you start the machine. Electrolysis of a sodium chloride solution with a ph value of 5 to 6 produces hypochlorite solutions and they can be used immediately after the machine has stopped running. They can be used to clean any premises. Making hypochlorite or sodium hypochlorite solution at home takes only a few minutes (10-30 minutes) by adding salt and water and distilled white vinegar (Reduce PH value of salt solution) in proportion to the machine. It is easy and cost effective to make at home and is ready to use once it is successfully made. I run several machines at a time, make multiple batches with various ppm for a fraction of the price.
