| Our Description |
| Thermo Electron Corporation, Thermo Environmental Instruments, now Thermo Scientific, is one of the most notable names in Ozone Analyzers. Model 49 U.V. Photometric Ozone Analyzer was top of the line. Thermo Electron a division of Thermo Fisher Scientific is a world leader in analytical and scientific equipment. The U.V. Photometer determines ozone concentration by measuring the attenuation of light due to ozone in the absorption cell, at a wavelength of 254 nm. The concentration of ozone is related to the magnitude of the attenuation.
The reference gas passes into the absorption cell to establish a zero light intensity reading. The solenoid then switches, and the sample gas passes through the absorption cell to establish a sample light intensity reading. The ratio of these two readings is a measure of the light absorbed by ozone in the sample at 254 nm. It is directly related to the concentration of ozone in the sample through the Beer-Lambert law. |
