Ozone is a powerful oxidizing agent used to kill microorganisms in air and water sources. Many municipal drinking water systems kill bacteria with ozone instead of the more common chlorine.

Ozone strongly absorbs at wavelengths below 400nm (UV), where our 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 produce a 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.
