    All maintenance and the first level of field troubleshooting are to be performed by the customer. NON- TELEDYNE API MANUFACTURED EQUIPMENT Equipment provided but not manufactured by Teledyne API is warranted and will be repaired to the extent and according to the current terms and conditions of the respective equipment manufacturers warranty.

  • Page 9: Principle Of Operation

    The detection of ozone molecules is based on absorption of 254 nm UV light due to an internal electronic resonance of the O 3 molecule. The Model 460H uses a mercury lamp constructed so that a large majority of the light emitted is at the 254nm wavelength. Light from the lamp shines through an absorption cell through which the sample gas being measured is passed.
