Overview
The GDT-500 ozone analyzer uses the principle of ultraviolet absorption to measure ozone concentration. Using the Beer Lambert law, measure the attenuation value of 254nm ultraviolet light passing through the sample using an ozone spectrophotometer. GDT-500 simultaneously measures sample gas and zero gas, performs real-time comparative calculations, and accurately measures ozone concentration.
