When it comes to reactive oxygen species, humans have discovered them for over 100 years. Reactive oxygen species can also be called triatomic oxygen, which is an allotrope of oxygen. It is a strong oxidant and has the ability to eliminate microorganisms, such as viruses and fungi. Moreover, compared to chlorine disinfection, it is faster. However, excessive disinfection is not advisable. Therefore, during the disinfection process, it is necessary to control the amount of reactive oxygen species properly.

So How Can we Determine the Content of Reactive Oxygen in Water?

To know the content of reactive oxygen in water, we need to use the ROS900 Reactive Oxygen Online Analyzer. This is a monitoring device specifically designed to detect reactive oxygen in water. This device offers multiple options. Timed measurement allows the instrument to be started for measurement at any time the user wants to monitor; continuous measurement enables one sample after another to be measured automatically, which can be used for product acceptance and related technical certifications; manual measurement allows the user to start the measurement at any time on site, which can be used for on-site experiments, comparisons, and equipment installation and commissioning.
