      DH30 Dissolved Hydrogen Tester
      DH30 Dissolved Hydrogen Meter : To measure Hydrogen Rich water, Dissolved Hydrogen concentration in the Hydrogen water generator.
      DH30 is designed based on ASTM Standard Test method. The precondition is to measure the concentration of dissolved hydrogen at one atmosphere for pure dissolved hydrogen water.
      The method is to convert the solution potential into the concentration of dissolved hydrogen at 25 degrees Celsius. The measurement upper limit is around 1.6 ppm.
      This method is the most convenient and fast method, but it is easy to be interfered by other reducing substances in the solution.
      Application: Pure dissolved hydrogen water concentration measurement.
