3. Understanding UV Photometry and Ozone Calibration
What is UV Photometry?
UV photometry is a technique that measures the concentration of ozone by detecting how much UV light is absorbed by ozone molecules. Since ozone absorbs UV light at specific wavelengths (around 254 nm), this method allows for precise quantification of ozone levels.
How the T703U Uses UV Photometry for Calibration
The T703U utilizes this principle by sending UV light through a sample of air containing ozone. The amount of light absorbed by the ozone is measured, and this data is used to calculate the ozone concentration. This method is highly accurate, reliable, and free from interference by other gases in the atmosphere.
