Measuring ozone

As the concentration and decomposition rate of ozone is extremely dependent on different parameters such as temperature, pressure, volume flow rate etc., medical ozone generators have to be equipped with a measurement device to ensure continuous concentration control.


Due to a powerful absorption band in the ultraviolet range (Hartley Band) with a max. absorption at 253.7 nm, a photometric procedure is a method of choice at this wavelength for continuous ozone concentration measurement, and has become an international standard on which other measuring methods base their values and correspondingly apply for calibrating, as summarized by the International Ozone Association IOA (Maschelein et al 1998; see Guidelines.
The Ozonosan units make use of the 590 nm absorption, calibrated by UV at 253,7.
