Product Overview:

This instrument adopts the ultraviolet absorption method. The basic working principle is: ozone can absorb ultraviolet light at a wavelength of 254nm, and the strength of absorption has a certain relationship with its concentration. The sample gas detection method is: a low-pressure mercury lamp emits ultraviolet light at 254nm wavelength, which irradiates the detection chamber. The detection chamber alternately passes through sample gas (containing ozone) and reference gas (sample gas with ozone removed). The concentration of O₃ in the sample gas is calculated using the Lambert-Beer law from the ratio of the two light intensities. The optical path uses two-way monitoring: one as the sample gas optical path for measurement, and the other as the reference optical path to monitor changes in the zinc lamp light source, automatically compensating for light source variations.
