Beer–Lambert law deviation is often observed. Here, we propose alternative wavelength 279.95 nm for ozone concentration measurement between 357 and 971 μL L −1 to preserve linearity. Sensor loses linearity below transmittance 0.2165, as sensor approaches saturation. We recommend measurement of ozone concentration above transmittance of 0.2165 for strong linear relation. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1013–1016, 2015
