The SYCOS KT-O3 is a portable and battery-buffered transfer test gas generator for ozone, NO and NO2. Oxygen in the air is split UV-photolytically after purification (particles and optionally by adsorbers) and converted to ozone. An externally applied NO test gas can be dynamically diluted and partially converted to NO2 by gas phase titration through the addition of ozone. The system can automatically compensate the influence of pressure, temperature and flow rate changes.
