Ozone is a powerful oxidizing agent used to bleach chemical and mechanical pulp. It is used as an alternative to chlorine or chlorine dioxide to remove lignin from wood pulp. It is often used in conjunction with oxygen and hydrogen peroxide to completely eliminate the need for chlorine-containing compounds in the manufacture of high-quality, white paper.

Ozone strongly absorbs at wavelengths below 400nm (UV) that the Kemtrak DCP007-UV LED process photometer can easily measure. The Kemtrak DCP007-UV uses a long life high performance UV LED light source with robust industrial grade fiber optics to provide drift and noise-free measurement with very high precision.

A proprietary dual wavelength four channel measurement technique and advanced digital electronics design allows deep absorbance measurement to 5 AU. A range of shorter optical pathlengths allow for deeper absorbance measurements. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation.
