Vaisala provides the H₂O₂ Calculator, an online tool allowing users to simulate bio-decontamination with vaporized hydrogen peroxide conditions in closed and open systems or under free evaporation conditions. By choosing the method and inputting phase parameters such as phase duration, temperature, injection rates, and liquid concentration, users can model their process and retrieve data on the condensation point, relative humidity, relative saturation, and achievable vH₂O₂ ppm concentration. Users can now understand how each para-meter impacts outcomes while learning the importance of precise measurement and control in vH₂O₂ bio-decontamination processes.
