SailheroXHOZ2000B Ozone Monitor adopts the ultraviolet photometry method. It is mainly used for the construction of various ambient air quality automatic monitoring stations at all levels, and can continuously and automatically monitor the concentration of ozone (O₃) in ambient air.
Sailhero XHOZ2000B monitor is based on ultraviolet absorption method, and O3 concentration in the air is monitored through the principle that O3 molecules generate electroresponse of different strengths before and after absorbing 254nm ultraviolet light. A hollow glass tube is irradiated by an ultraviolet lamp with an emission wavelength of 254nm; through solenoid valve switching, the glass tube is alternately filled with sample gas and O3-eliminated reference gas. The ratio of light intensity between O3-eliminated reference gas and sample gas is I0/I, through this value, the concentration of O3 can be calculated by Lambert-Beer formula.
