NOx reactor
A Pirex glass reactor, with a volume of 20 liters, allows testing directly the photocatalytic activity of the ceramic products: the tiles lay inside the reactor, at the bottom, and they can be directly radiated by different source of lights.
The atmosphere inside is rich in nitrogen oxides molecules, that are automatically monitored by a chemiluminescence, which is an instrument able to take over the concentration of this kind of pollutant.
An environment in which you see the tile in action against pollution is perfectly created.
