05509F DCN6409 19 3. PRINCIPLE OF OPERATION The detection of ozone molecules is based on ab sorption of 254 nm UV light due to an internal electronic resonance of the O 3 molecule. The Model 465 uses a m ercury lamp constructed so that a large majority of the light emitted is at the 254nm wavelength.
Teledyne API Model 465L O 3 Monitor Operation Manual 20 05509F DCN6409 The intensity of light is converted into a vo ltage by a high resolution A/D (analog-to-digital) converter. The digitized signal and other vari ables are used by the CPU to compute the concentration using the above formula.
