HOW DO WE VERIFY AND TEST FOR THE DISSOLVED OXYGEN CONTENT OF ACTIVATED STABILIZED OXYGEN?
The standard method of testing for dissolved oxygen in liquids containing less than 19.99 p.p.m. (parts per million) of dissolved oxygen is by automatic calibration using the conducto-metric oxygen probe method. For solutions containing dissolved oxygen levels higher than 20.0 p.p.m, other methods must be used including colorimiter (DPD Test Tabs) and titration methods. It should also be noted that the water purification and water quality control industry has influenced the development of numerous testing methods to determine the oxygen (O2) content of water. These various test devices can test for as few as 1 ppm to as many as 20 ppm. No electronic testing device available today will measure O2 concentrations in water in excess of approximately 20 ppm. The main reason why devices are not available is that most applications for oxygen testing are for the waste water management (sewage) industries. In these applications the amount of available oxygen in waste water or raw sewage is well
